Time-based One-Time Password algorithm (TOTP) is an algorithm that computes a one-time password from a shared secret key and the current time.

Time-based One-Time Password algorithm (TOTP) is an algorithm that computes a one-time password from a shared secret key and the current time.

TOTP is based on HOTP with a timestamp replacing the incrementing counter.

The current timestamp is turned into an integer time-counter (TC) by defining the start of an epoch (T0) and counting in units of a time interval (TI).
