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 HMAC-based one …

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, 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 seconds. …

A Time-based One-Time Password (TOTP) serves as a form of two-factor authentication (2FA). Other terms for TOTP include app-based authentication, software tokens, or soft tokens.

2 days ago · TOTP is an algorithm that uses time as an input to grant users one-time access to an application. Learn how TOTP authentication works and why it’s a strong 2FA factor.

A time-based one-time password (TOTP) is a form of two-factor authentication (2FA) that generates a one-time password (OTP) as the second factor, which changes at regular intervals.

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).

May 19, 2025 · TOTP (Time-Based One-Time Password) is a secure, standards-based MFA method that generates short-lived codes on the user’s device. This guide explains how TOTP works and why …

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?

Oct 27, 2025 · Time-Based One-Time Password (TOTP) systems represent a significant advancement over HOTP, addressing many of its practical limitations while introducing new security benefits.
