  2. Jun 21, 2024 · Time-based One-Time Passwords (TOTP) TOTPs are generated using the current time and a shared secret key. This means that the OTP changes at regular intervals, typically every 30 seconds. This method ensures that each OTP is unique and time-bound, adding an extra layer of security.

    Sometimes a site or service requires that TOTP be used in tandem with your regular password to access your account. TOTP can help protect you against weak or reused passwords, but it is not a substitute or replacement for strong and unique passwords. One-time passwords can also be useful when you’re accessing an account over an insecure or open net...

    Time-based one-time passwords are often seen as a two-step verification option rather than true two-factor (or second-factor) authentication like U2F-compatible security keys. Though one-time passwords are often part of a two-factor security system, using TOTP doesn’t automatically give you second-factor security. When your one-time password is sto...

One-time passwords are created by an algorithm, that generates a unique value for each OTP by factoring in contextual information, like time-based data or previous login events.

TOTPs can be used in place of, or as an additional factor alongside, traditional, longer-lived two-factor ...
