Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) that uses the current time as a source of uniqueness. As an extension of the HMAC-based one-time password algorithm (HOTP), it has been adopted as Internet Engineering Task Force (IETF) standard RFC … See more Through the collaboration of several OATH members, a TOTP draft was developed in order to create an industry-backed standard. It complements the event-based one-time standard HOTP, and it offers end user organizations … See more Unlike passwords, TOTP codes are single-use, so a compromised credential is only valid for a limited time.

WebJun 26, 2024 · Small question regarding a TOTP generation algorithm please. I am building a TOTP generation algorithm. In order to do so, I am using HMAC SHA1. The result is correct, I used many time this HMAC SHA1 generated TOTP to authenticate myself to servers, I had confirmation the TOTP is correct, very happy. 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.
