Generate TOTP 2FA codes from a Base32 secret key. Use this to test Google Authenticator, Authy, or any RFC 6238 implementation.
🔒 Secret key stays in your browser. No data is sent to any server.
What is TOTP?
- TOTP (Time-based One-Time Password) is an algorithm (RFC 6238) that generates a 6-digit code that changes every 30 seconds.
- Used by Google Authenticator, Authy, Microsoft Authenticator, and most 2FA apps.
- The secret key is a Base32 string shared between your app and the authenticator during setup.
- This tool is for testing and development — use it to verify your TOTP implementation produces the correct codes.
