Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Principles of Consolidation Unaudited Interim Condensed Consolidated Financial Statements 10-K, Use of Estimates Marketable Securities available-for-sale Revenue Recognition — Revenue from the Company’s premium services is recognized on a daily basis over the subscription term as the services are delivered, provided that there is persuasive evidence of an arrangement, the fee is fixed or determinable and collectability is deemed reasonably assured. Subscription periods range from monthly to ten years. The Company’s software cannot be run on another entity’s hardware and customers do not have the right to take possession of the software and use it on their own or another entity’s hardware. Revenue from the Company’s audio services is recognized upon actual usage of audio minutes or the expiration of audio minutes purchased in prepaid plans. Any unbilled audio revenue is accrued for in the period the usage occurs. The Company’s multi-element arrangements typically include subscription and professional services, which may include development services. The Company evaluates each element within the arrangement to determine if they can be accounted for as separate units of accounting. If the delivered item or items have value to the customer on a standalone basis, either because they are sold separately by any vendor or the customer could resell the delivered item or items on a standalone basis, the Company has determined that the deliverables within these arrangements qualify for treatment as separate units of accounting. Accordingly, the Company recognizes revenue for each delivered item or items as a separate earnings process commencing when all of the significant performance obligations have been performed and when all of the revenue recognition criteria have been met. Professional services revenue recognized as a separate earnings process under multi-element arrangements has been immaterial to date. In cases where the Company has determined that the delivered items within its multi-element arrangements do not have value to the customer on a stand-alone basis, the arrangement is accounted for as a single unit of accounting and the related consideration is recognized ratably over the estimated customer life, commencing when all of the significant performance obligations have been delivered and when all of the revenue recognition criteria have been met. Revenue from multi-element arrangements accounted for as a single unit of accounting which do not have value to the customer has been immaterial to date. Concentrations of Credit Risk and Significant Customers For the three months ended March 31, 2016 and 2017, no customers accounted for more than 10% of revenue. As of December 31, 2016 and March 31, 2017, no customers accounted for more than 10% of accounts receivable. Goodwill Long-Lived Assets and Intangible Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets, including intangible assets, may not be recoverable. When such events occur, the Company compares the carrying amounts of the assets to their undiscounted expected future cash flows. If this comparison indicates that there is impairment, the amount of the impairment is calculated as the difference between the carrying value and fair value. Through March 31, 2017, the Company recorded no material impairments. Foreign Currency Translation — period-end Derivative Financial Instruments — The Company had net foreign currency losses of $0.4 million for the three months ended March 31, 2016, and net foreign currency gains of $0.1 million for the three months ended March 31, 2017, included in other (expense) income in the condensed consolidated statements of operations. As of March 31, 2017, the Company had one foreign currency forward contract outstanding denominated in British Pound/Euro, with a maturity of one month and a notional amount equivalent to $3.1 million. Net realized and unrealized gains and losses on the forward contract included in foreign currency net gains and losses was a net gain of $10,000 for the three months ended March 31, 2017. Stock-Based Compensation — with-or-without Income Taxes The Company evaluates its uncertain tax positions based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings is more likely than not to be realized. Potential interest and penalties associated with any uncertain tax positions are recorded as a component of income tax expense. Segment Data The Company’s revenue by geography (based on customer address) is as follows (in thousands): Three Months Ended March 31, 2016 2017 Revenues: United States $ 57,251 $ 141,178 United Kingdom 6,186 11,496 International—all other 16,297 34,784 Total revenue $ 79,734 $ 187,458 Amounts for the three months ended March 31, 2016 presented in the Company’s revenue by service cloud (product grouping) table below include reclassifications between product groups to conform to the current year classification of the Company’s and the GoTo Business’ products (in thousands): Three Months Ended March 31, 2016 2017 Revenues: Communications and Collaboration cloud $ 9,220 $ 89,733 Identity and Access Management cloud 45,979 60,546 Customer Engagement and Support cloud 24,535 37,179 Total revenue $ 79,734 $ 187,458 Guarantees and Indemnification Obligations — by-laws. In the ordinary course of business, the Company enters into agreements with certain customers that contractually obligate the Company to provide indemnifications of varying scope and terms with respect to certain matters including, but not limited to, losses arising out of the breach of such agreements, from the services provided by the Company or claims alleging that the Company’s products infringe third-party patents, copyrights, or trademarks. The term of these indemnification obligations is generally perpetual. The maximum potential amount of future payments the Company could be required to make under these indemnification obligations is, in many cases, unlimited. Through March 31, 2017, the Company has not experienced any losses related to these indemnification obligations. Net Income (Loss) Per Share — The Company excluded the following options to purchase common shares and restricted stock units from the computation of diluted net loss per share because they had an anti-dilutive impact (in thousands): Three Months Ended March 31, 2016 2017 Options to purchase common shares 707 234 Restricted stock units 1,548 1,806 Total options and restricted stock units 2,255 2,040 The Company recorded a net loss in both the three months ended March 31, 2016 and 2017 and all outstanding options to purchase common shares and restricted stock units have been excluded from the computation of diluted net loss per share as they had an anti-dilutive impact.

Fair Value of Financial Instruments	3. Fair Value of Financial Instruments The carrying value of the Company’s financial instruments, including cash equivalents, restricted cash, accounts receivable and accounts payable, approximate their fair values due to their short maturities. The Company’s financial assets and liabilities are measured using inputs from the three levels of the fair value hierarchy. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The three levels are as follows: • Level 1: Unadjusted quoted prices for identical assets or liabilities in active markets accessible by the Company at the measurement date. • Level 2: Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The following table summarizes the basis used to measure certain of the Company’s financial assets that are carried at fair value (in thousands): Fair Value Measurements at December 31, 2016 Level 1 Level 2 Level 3 Total Cash equivalents — money market funds $ 11,599 $ — $ — $ 11,599 Short-term marketable securities: U.S. government agency securities 34,961 8,001 — 42,962 Corporate Bond Securities — 12,748 — 12,748 Fair Value Measurements March 31, 2017 Level 1 Level 2 Level 3 Total Cash equivalents — money market funds $ 25,354 — — $ 25,354 Short-term marketable securities: — U.S. government agency securities 19,886 1,502 — 21,388 Corporate bond securities — 7,998 — 7,998 Bank deposits, corporate bonds and certain U.S. government agency securities are classified within the second level of the fair value hierarchy as the fair value of those assets are determined based upon quoted prices for similar assets.

Business Combinations [Abstract]
Acquisitions	4. Acquisitions Acquisition-Related Costs In the three months ended March 31, 2016 and 2017, acquisition-related costs were $3.2 million and $31.9 million, respectively. Acquisition-related costs are associated with the acquisitions of businesses and intellectual property and include transaction, transition and integration-related charges (including legal, accounting and other professional fees, severance, and retention bonuses) and subsequent adjustments to our initial estimated amount of contingent consideration associated with acquisitions. Acquisition-related costs for the first quarter of 2016 were primarily comprised of retention bonuses related to the Company’s 2014 and 2015 acquisitions. Acquisition-related costs for the first quarter of 2017 were primarily related to the Merger and included $17.1 million in transaction, transition and integration-related expenses, $7.9 million in integration-related severance costs and $6.9 million of retention-based bonuses as well as $1.6 million related to the Company’s 2015 and 2016 acquisitions. 2017 Acquisitions GetGo Merger On January 31, 2017, the Company completed its Merger with GetGo, a wholly-owned subsidiary of Citrix, pursuant to which the Company acquired Citrix’s GoTo Business. In connection with the Merger, the Company issued 26.9 million shares of its common stock to Citrix stockholders and an additional 0.4 million of the Company’s restricted stock units in substitution for certain outstanding Citrix restricted stock units held by GetGo employees. Based on the Company’s closing stock price of $108.10 on January 31, 2017 as reported by the NASDAQ Global Select Market, the total value of the shares of LogMeIn common stock issued to Citrix stockholders in connection with the Merger was $2.9 billion. The Merger is being accounted for under the acquisition method of accounting with the operations of the GoTo Business included in the Company’s operating results since the date of acquisition. Since the Merger, the operating costs of the GoTo Business are being integrated with the operating costs of the Company. During the three months ended March 31, 2017, the Company recorded revenue of $100.5 million, amortization of acquired intangibles of $31.0 million, and acquisition-related transaction, transition and integration costs of $30.3 million directly attributable to the acquisition within its condensed consolidated financial statements. The acquisition method of accounting requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The preliminary determination of the fair value of assets acquired and liabilities assumed has been recognized based on management’s estimates and assumptions using the information about facts and circumstances that existed at the acquisition date. While the Company uses its best estimates and assumptions as part of the purchase price allocation process to value the assets acquired and liabilities assumed on the acquisition date, its estimates and assumptions are subject to refinement. Fair value estimates are based on a complex series of judgments about future events and uncertainties and rely heavily on estimates and assumptions. The judgments used to determine the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, can materially impact the Company’s results of operations. The finalization of the purchase accounting assessment will result in a change in the valuation of assets acquired and liabilities assumed and may have a material impact on the Company’s results of operations and financial position. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with a corresponding offset to goodwill to reflect additional information received about facts and circumstances which existed at the date of acquisition. The Company records adjustments to the assets acquired and liabilities assumed subsequent to the purchase price allocation period in the Company’s operating results in the period in which the adjustments were determined. The size and breadth of the Merger will necessitate the use of this measurement period to adequately analyze and assess a number of the factors used in establishing the fair value of certain tangible and intangible assets acquired and liabilities assumed as of the acquisition date and the related tax impacts of any changes made. Any potential adjustments made could be material in relation to the preliminary values presented below. The following table summarizes the fair value (in thousands) of the assets acquired and liabilities assumed at the date of acquisition: Purchase consideration: Company common shares issued $ 2,904,487 (1) Restricted stock units issued 16,692 (2) Total estimated purchase consideration $ 2,921,179 Estimated fair value of assets acquired and liabilities assumed: Cash 24,215 Accounts receivable 50,098 Property and equipment 59,715 Prepaid expense and other current assets 21,713 Other assets 4,448 Intangible assets (weighted average useful life): (3) Completed technology (9 years) 385,000 Customer relationships (8 years) 756,000 Tradenames and trademark (9 years) 65,100 Accounts payable (11,030 ) Accrued liabilities (26,886 ) Deferred revenue, current and noncurrent (82,643 ) Other long-term liabilities (996 ) Deferred tax liability, net (426,081 ) Goodwill $ 2,102,526 (1) Represents the fair value of the 26.9 million new shares of the Company’s common stock (plus cash in lieu of fractional shares) issued to Citrix stockholders, based on the fair value per share of the Company’s common stock of $108.10 per share, which was the closing price of the Company’s common stock on the NASDAQ Global Select Market on January 31, 2017. (2) Represents the fair value of the 0.4 million Company restricted stock units issued by the Company in substitution for certain outstanding Citrix restricted stock units held by GetGo employees, pursuant to the terms of the Merger. These Company restricted stock units were issued on the same terms and conditions as were applicable to the outstanding Citrix restricted stock units held by the GetGo employees immediately prior to the Merger date (including the same vesting and forfeiture provisions). The aggregate fair value of those awards ($48.2 million) is based on the fair value per share of the Company’s common stock of $108.10 per share, which was the closing price of the Company’s common stock on the NASDAQ Global Select Market on the January 31, 2017. Of that amount, $18.0 million was related to pre-combination (3) The weighted average useful life of identifiable intangible assets acquired in the transaction is 8.4 years. The completion of the Merger and the acquisition of the GoTo Business is expected to expand the Company’s reach in its key markets, including the web conferencing market, and provide the platform, customer base, and team to develop and compete in the next generation of intelligent, real-time collaboration and communication offerings. The acquisition of the GoTo Business also further strengthens the Company’s resources to better support a larger, more diverse and more global customer base, and increase scale and elevate the Company’s strategic position within key accounts. Goodwill of $2.1 billion was recognized for the excess purchase consideration over the estimated fair value of the assets acquired. Goodwill and intangible assets recorded as part of the acquisition are not deductible for tax purposes. The Company recorded a deferred tax liability, net of deferred tax assets, of $426.1 million primarily related to the amortization of intangible assets which cannot be deducted for tax purposes, partially offset by deferred tax assets primarily related to the pre-combination The Company and Citrix entered into a transition services agreement, pursuant to which each party will provide to the other party certain services on a transitional basis following the completion of the Merger to facilitate the transition of the GoTo Business to the Company. Among other services, the transition services generally relate to information technology and security operations, facilities, human resources support and accounting and finance support. As of March 31, 2017, the Company has incurred $2.6 million of costs related to the transition services agreement.

Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes The Company recorded a benefit for federal, state, and foreign taxes of $0.2 million and $15.9 million on a loss before income taxes of $1.3 million and $34.4 million for the three months ended March 31, 2016 and 2017, respectively, resulting in an effective tax rate of 19% and 46%, respectively. The effective income tax rates for the three months ended March 31, 2016 and 2017 were impacted by profits earned in certain foreign jurisdictions, primarily our Irish subsidiaries, which are subject to significantly lower tax rates than the U.S. federal statutory rate. The effective income tax rate for the three months ended March 31, 2017 was also impacted by the expected non-deductibility of certain transaction costs related to the Merger and $2.3 million of discrete income tax benefits related to excess tax deductions on stock compensation now recorded as a tax benefit due to our adoption of ASU 2016-09 as well as a $2.3 million tax benefit related to discrete integration-related activity. Deferred tax assets, related valuation allowances, current tax liabilities, and deferred tax liabilities are determined separately by tax jurisdiction. In making these determinations, the Company estimates deferred tax assets, current tax liabilities, and deferred tax liabilities, and the Company assesses temporary differences resulting from differing treatment of items for tax and accounting purposes. As of March 31, 2017, the Company maintained a full valuation allowance against the deferred tax assets of its Hungarian subsidiary. This entity has historical tax losses and the Company concluded it was not more likely than not that these deferred tax assets are realizable. The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Company’s income tax returns from 2011 are open to examination by federal, state, and/or foreign tax authorities. In the normal course of business, the Company and its subsidiaries are examined by various taxing authorities. The Company regularly assesses the likelihood of additional assessments by tax authorities and provides for these matters as appropriate. Audits by tax authorities typically involve examination of the deductibility of certain permanent items, limitations on net operating losses and tax credits. Although the Company believes its tax estimates are appropriate, the final determination of tax audits could result in material changes in its estimates. The Company has recorded a liability related to uncertain tax positions of $1.5 million and $2.6 million as of December 31, 2016 and March 31, 2017, respectively. The Company’s policy is to record estimated interest and penalties related to the underpayment of income taxes or unrecognized tax benefits as a component of its income tax provision. The Company recognized $4,000 and $14,000 of interest expense for the three months ended March 31, 2016 and 2017, respectively.

Pursuant to the plan, the Company intends to return to its stockholders approximately 75% of its free cash flow over the period, up to $700 million, through a combination of share repurchases and dividends. As part of this capital return plan, the Company expects to initiate a quarterly cash dividend of $0.25 per share, with the first dividend under this plan to be paid on May 26, 2017 to stockholders of record as of May 10, 2017. The Company recorded a dividend payable of $13.2 million in accrued liabilities based on the Company’s stockholders of record as of March 31, 2017. The Company’s Board of Directors will continue to review this capital return plan for potential modifications based on the Company’s financial performance, business outlook and other considerations. The timing and number of shares to be repurchased will depend upon prevailing market conditions and other factors, including potential tax restrictions which may be imposed on the Company related to the Merger and the resolution of the Company’s related private letter ruling from the Internal Revenue Service. Additionally, the Company’s credit facility contains certain financial and operating covenants that may restrict its ability to pay dividends in the future. For the three months ended March 31, 2016 and 2017, the Company repurchased 164,127 and 76,660 shares of its common stock at an average price of $50.98 and $97.38 per share, respectively, for a total cost of $8.4 million and $7.5 million, respectively.

The Company awards restricted stock units as the principal equity incentive award.

Until 2012, the Company generally granted stock options as the principal equity incentive award. Options generally vest over a four-year period and expire ten years from the date of grant. Certain stock-based awards provide for accelerated vesting if the Company experiences a change in control. As March 31, 2017, there were 7.7 million shares available for grant under the 2009 Plan. The Company’s Board of Directors and stockholders approved an amendment and restatement of the Company’s 2009 Stock Incentive Plan, which was effective on January 31, 2017, to increase the number of shares of the Company’s common stock that may be issued under the plan by an additional 4,500,000 shares and to extend the term of the plan to December 5, 2026.

Debt Disclosure [Abstract]
Credit Facility	12. Credit Facility On February 18, 2015, the Company entered into a multi-currency credit agreement with a syndicate of banks (the “Credit Agreement”), pursuant to which a secured revolving credit facility of up to $100.0 million in the aggregate was made available to the Company. On January 22, 2016, the Company entered into the First Amendment to the Credit Agreement, pursuant to which the Company exercised its option to increase the credit facility to up to $150.0 million in the aggregate with an option to further increase the credit facility by an additional $50.0 million. On February 1, 2017, the Company entered into an Amended and Restated Credit Agreement (the “Amended Credit Agreement”), which amended and restated the Credit Agreement. The Amended Credit Agreement increased the Company’s secured revolving credit facility from $150.0 million to $400.0 million in the aggregate, and permits the Company to increase the revolving credit facility and/or enter into one or more tranches of term loans up to an additional $200.0 million. The Amended Credit Agreement also extended the maturity date of the revolving credit facility to February 1, 2022. The outstanding debt balance was $30.0 million as of March 31, 2017. The Company may prepay the loans or terminate or reduce the commitments in whole or in part at any time, without premium or penalty. The Company repaid $15.0 million of the outstanding borrowings on each of April 4, 2017 and May 3, 2017, eliminating its remaining outstanding debt balance. The Company and its subsidiaries expect to use the credit facility for general corporate purposes, including, but not limited to, the potential acquisition of complementary products or businesses, share repurchases, as well as for working capital. Loans under the Amended Credit Agreement bear interest at variable rates which reset every 30 to 180 days depending on the rate and period selected by the Company as described below. As of March 31, 2017, the annual rate on the $30.0 million revolving loan was 2.0625% and was renewed at 2.25% on April 3, 2017. The average interest rate on borrowings outstanding for the period ending March 31, 2017 was 2.146%. The quarterly commitment fee on the undrawn portion of the credit facility ranges from 0.15% to 0.30% per annum, based upon the Company’s total leverage ratio. As of March 31, 2017, the fair value of the credit facility approximated its book value. The Amended Credit Agreement contains customary affirmative and negative covenants, subject to customary and other exceptions for a credit facility of this size and type, each as further described in the Amended Credit Agreement. As of March 31, 2017, the Company was in compliance with all financial and operating covenants of the Amended Credit Agreement. Any failure to comply with the financial or operating covenants of the Amended Credit Agreement would prevent the Company from being able to borrow additional funds, and would constitute a default, permitting the lenders to, among other things, accelerate the amounts outstanding, including all accrued interest and unpaid fees, under the credit facility and to terminate the credit facility. As of March 31, 2017, the Company had $2.7 million of origination costs recorded in other assets. The Company incurred approximately $2.0 million of origination costs in connection with the Amended Credit Agreement executed in February 2017. As permitted by FASB issued ASU 2015-15,

Revenue Recognition	Revenue Recognition — Revenue from the Company’s premium services is recognized on a daily basis over the subscription term as the services are delivered, provided that there is persuasive evidence of an arrangement, the fee is fixed or determinable and collectability is deemed reasonably assured. Subscription periods range from monthly to ten years. The Company’s software cannot be run on another entity’s hardware and customers do not have the right to take possession of the software and use it on their own or another entity’s hardware. Revenue from the Company’s audio services is recognized upon actual usage of audio minutes or the expiration of audio minutes purchased in prepaid plans. Any unbilled audio revenue is accrued for in the period the usage occurs. The Company’s multi-element arrangements typically include subscription and professional services, which may include development services. The Company evaluates each element within the arrangement to determine if they can be accounted for as separate units of accounting. If the delivered item or items have value to the customer on a standalone basis, either because they are sold separately by any vendor or the customer could resell the delivered item or items on a standalone basis, the Company has determined that the deliverables within these arrangements qualify for treatment as separate units of accounting. Accordingly, the Company recognizes revenue for each delivered item or items as a separate earnings process commencing when all of the significant performance obligations have been performed and when all of the revenue recognition criteria have been met. Professional services revenue recognized as a separate earnings process under multi-element arrangements has been immaterial to date. In cases where the Company has determined that the delivered items within its multi-element arrangements do not have value to the customer on a stand-alone basis, the arrangement is accounted for as a single unit of accounting and the related consideration is recognized ratably over the estimated customer life, commencing when all of the significant performance obligations have been delivered and when all of the revenue recognition criteria have been met.
