WebI also decided to learn how it worked. Luckily, the algorithm—the Time-Based One-Time Password Algorithm (TOTP)—is very simple. Sharing Secrets… First, your authenticator app and the server must agree on a shared secret. The most common way this happens is that the server generates a secret and then displays a QR code to scan. WebTOTP two-factor authentication . Guacamole supports TOTP as a second authentication factor, layered on top of any other authentication extension, including those available from the main project website, providing base requirements for key storage and enrollment are met.

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, which creates the potential for phishing attacks.
