One-time passcodes are generated using open standards developed by the Initiative for Open Authentication (OATH) (which is unrelated to OAuth). TOTP drives Google Authenticator and many other compatible systems. To make TOTP work with time, the counter is defined as the number of intervals that have passed since a reference point in time. Google-Authenticator-compatible TOTP systems standardized on thirty-second intervals and the Unix epoch.

One weakness of TOTP is that the same combination of secret key and timestamp always generates the same 6-digit code.
