WebAug 18, 2024 · The basic idea behind TOTP is to use a shared secret to produce digital signatures 2 of timestamps. At a high level, the algorithm is as follows: The secret is produced on the server and communicated to the 2FA client. This is usually done via a QR code, but you can also just type it in. 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. However, users must enter TOTP codes into an authentication page, … See more • Step by step Python implementation in a Jupyter Notebook • Designing Docker Hub Two-Factor Authentication, (section "Using Time-Based One-Time Password (TOTP) Authentication").

WebMar 16, 2024 · HOTP (HMAC based OTP algorithm) is also often referred to as event-based one time pass. HOTP authentication requires two inputs. The first one is the seed shared by the server and the HOTP token, this is a constant that validates the OTPs. The second one is a counter, which is a variable stored on the server and the token (these two are ...
