What is a TOTP?
A time-based one-time password (or passcode) is a code generated with an algorithm that uses a shared secret and the current time as inputs. A TOTP code changes at set time intervals – usually 30 to 90 seconds – and is very difficult for attackers to compromise.
How TOTP authenticators help your app
Primed for wide adoption
TOTP does not require users to have new hardware, remember passwords, or even have network connectivity.
Elevated security
Authenticator apps are tied to a user’s device, making them immune to SIM swapping and more secure than SMS 2FA.
One factor, two factor
TOTP authentication can easily fit into step-up or multi-factor authentication flows.
