Time-based one-time password (TOTP) is a computer algorithm that generates a one-time password (OTP) using the current time as a source of uniqueness. As an extension of the …

Time-based One-time Password (TOTP) is a time-based OTP. The seed for TOTP is static, just like in HOTP, but the moving factor in a TOTP is time-based rather than counter-based.

TOTP.APP - is a online generator of one-time passwords, based on TOTP (RFC 6238) algorithm. A web-based analog of the Google Authenticator mobile application.

TOTP stands for Time-based One-Time Passwords and is a common form of two-factor authentication (2FA). Unique numeric passwords are generated with a standardized algorithm …

TOTP uses two inputs: a shared secret key (known only to the server and the user’s authenticator app) and the current timestamp. Because this algorithm is time-driven, it produces a new code …

TOTP, as we’ve established, is a type of OTP that uses time as a factor in calculating the code. The factor changes as time passes, meaning that a new code is generated every 30 to 60 …

Jun 2, 2025 · If a user's traditional password is stolen or compromised, an attacker cannot gain account access without the TOTP, which expires quickly. How does a TOTP work?

Nov 8, 2025 · TOTP (Time-based One-Time Password) is a simple, widely used method for generating short-lived numeric codes from a shared secret and the current time (RFC 6238).

Sep 11, 2023 · What is a TOTP? We’ve established the key principles behind OTPs, so let’s get a bit more specific and find out what a TOTP is. The latter half of the acronym stands for “one …

Time-Based One-Time Passwords (TOTP) are gaining traction because they add a time-sensitive layer of protection beyond just a username and password.
