This can be used with non-Google apps that support it , but the most common use will be to login to Google or other accounts in a web browser. You will probably need [[com.google.zxing.client.android]] to be installed, though for some accounts it may be possible to type in keys. The Google Authenticator project includes implementations of one-time passcode generators for several mobile platforms, as well as a pluggable authentication module (PAM). One-time passcodes are generated using open standards developed by the Initiative for Open Authentication (OATH) (which is unrelated to OAuth). These implementations support the HMAC-Based One-time Password (HOTP) algorithm specified in RFC 4226 and the Time-based One-time Password (TOTP) algorithm specified in RFC 6238. .
