Frequently Asked Questions
What is TOTP?
TOTP (Time-based One-Time Password) is a temporary 6-digit code that changes every 30 seconds, used as a second factor in two-factor authentication (2FA). It is computed from a shared secret and the current time.
Is my secret safe?
Absolutely. All TOTP computation happens locally in your browser using JavaScript. Your secret is never transmitted to or stored on any server.
