About

TOTP (Time-based One-Time Password) is the standard algorithm (RFC 6238) behind most two-factor authentication apps including Google Authenticator, Authy, Microsoft Authenticator, and 1Password. It combines a shared secret key with the current time to generate a short-lived 6-digit verification code that changes every 30 seconds.
Your secret key never leaves your browser. All TOTP code generation happens 100% client-side using JavaScript. No data is sent to any server. You can verify this by checking the network tab in your browser developer tools. The source code is open on GitHub
