WebTime-based one-time passwords – A TOTP is valid for a set period of time – usually 30 or 60 seconds. Such a password must be used within that timeframe or it will become invalid, meaning the user will need to request another one. Hash-based one-time passwords – An HOTP remains valid until the user requests another password.
