Google Authenticator is a software-based authenticator by Google. It implements multi-factor authentication services using the time-based one-time password (TOTP; specified in RFC 6238) and HMAC-based one-time password (HOTP; specified in RFC 4226), for authenticating users of software applications.[2]
When logging into a site supporting Authenticator (including Google services) or using Authenticator-supporting third-party applications such as password managers or file hosting services, Authenticator generates a six- to eight-digit one-time password which users must enter in addition to their usual login details.

Google provides Android,[3] Wear OS,[4] BlackBerry, and iOS[5] versions of Authenticator.
An official open-source fork of the Android app is available on GitHub.[6] However, this fork was archived in Apr 6, 2021 and is now read only.[7]
Current software releases are proprietary freeware.[8]
