Time-based one-time passwords (TOTP)
A time-based one-time password (TOTP) is a type of two-factor authentication that uses a time-based six-digit number to replace a stored secret passphrase.
Instead of entering a passphrase, a confirmation code is entered via a mobile app or from an application on the Computer of the user is generated.
The use of a TOTP instead of a conventional password provides an additional level of security that this additionally expires after a certain time.
