What is TOTP?
TOTP (Time-based One-Time Password) is an algorithm that generates a one-time password using the current time and a shared secret key. It's the standard used by Google Authenticator, Microsoft Authenticator, and other 2FA apps.
TOTP codes typically refresh every 30 seconds and are 6 digits long.
