What is Google Authenticator – Google Authenticator is a software-based authenticator by Google that implements a two-step verification service using the Time-Based One-Time Password Algorithm (TOTP; specified in RFC 6238) and the HMAC-based One-Time Password algorithm (HOTP; specified in RFC 4226), for authenticate you as a user of the software application.

When logging in to an Authenticator-enabled site (including Google services) or using a third-party Authenticator-enabled application such as a password manager or file hosting service, Authenticator generates a one-time six to eight-digit password that the user must enter in addition to their usual login details.

Google provides an Android version of Authenticator,[3] BlackBerry, and iOS. The official open-source fork of the Android app is available on GitHub. However, this Fork has not been updated since 2020. Likewise, for older versions of the Google Authenticator app for iOS and BlackBerry, the source code is also freely available. However this source code also hasn’t been updated for years.

To use Authenticator, the app is first installed on the smartphone. This has to be set up for each site that the site will use to provide users with a shared secret key via a secure channel, to be stored in the Authenticator app. This secret key will be used for all future logins to the site.

To sign in to a site or service that uses two-factor authentication and supports Authenticator, the user provides a username and password to the site. The site then calculates (but does not display) the required six-digit one-time password and prompts the user to enter it. The user runs the Authenticator application, which independently calculates and displays the same password, which the user types, authenticating their identity so that not everyone can freely log in for the security of your account.
