Google Authenticator

Google Authenticator is an application that implements Time-based One-time Password Algorithm (TOTP) security tokens in mobile apps made by Google.The Authenticator can also generate codes for third-party applications or file hosting services.Previous versions of the software were open source but subsequent releases are proprietary.

Working
The service provider generates an 80-bit secret key for each user (in contravention of RFC 4226 §4[33]). This is provided as a 16, 24 or 32 character base32 string or as a QR code. The client creates an HMAC-SHA1 using this secret key.
users will install the Authenticator app on their smartphone to log into a site or service that uses two-factor authentication, they provide user name and password to the site and run the Authenticator app which produces an additional six-digit one-time password. The user provides this to the site, the site checks it for correctness and authenticates the user.
