Authy (also known as Twilio Authy)[1] is a two-factor authentication (2FA) mobile app. Originally released in 2012 by Authy Inc., the app was acquired by American communications firm Twilio in 2015.[2][3] Authy provides online backup for security tokens, and users must register an account with a phone number prior to using the app.[4] It supports the Android and iOS operating systems.[5] In 2022 and 2024, Authy experienced data breaches involving user accounts and phone numbers.[6][7]
History
Authy Inc. founders Daniel Palacio and Gleb Chuvpilo were accepted into the Y Combinator startup accelerator program in late 2011.[8] The initial version of Authy was released in August 2012.[2] In 2014, Authy Inc. raised $3 million in a series A round.[9][10] At the time, Authy charged companies for its API, which allowed websites to validate each login with a one-time password (OTP) delivered to the user's device. Companies that implemented the API were billed every time a user signed up or logged in via Authy.[9] Twilio acquired Authy Inc. in February 2015 and indicated that Authy would be integrated with Twilio's API.[3][11]
Authy maintained a Chrome App and browser extension for Google Chrome from April 2014 until the deprecation of the Chrome App platform in 2020.[12][13] The Windows and macOS desktop applications for Authy were released in 2017,[14] followed by a beta version of the Linux application in 2020.[15] Authy discontinued its Windows, macOS, and Linux applications in August 2024.[5][16] Because Authy did not include a data export feature, users who switched to another two-factor authentication (2FA) app had to disable 2FA on each of their accounts before re-enabling it with the new app.[5][17]
Security incidents
Twilio employees were targeted by an SMS phishing campaign in August 2022 that resulted in a data breach impacting 209 of Twilio's client organizations, after which the hackers compromised 93 Authy accounts and linked them to their own devices.[6][18][19][20] In a July 2024 data breach, hacker group ShinyHunters used an unsecured Twilio API to collect the phone numbers of 33 million Authy accounts.[7][21][22][23]
