About this tool

Enter a base32 authentication secret to generate the current TOTP / 2FA code used by authenticator apps such as Google Authenticator or Authy. The code rotates every 30 seconds and the countdown shows when it will change. Everything runs locally in your browser.

How to use
  1. Paste your base32 authentication secret (the key from your 2FA setup).
  2. Read the current 6-digit code.
  3. Copy the code into the login form before the countdown ends.
Is my secret uploaded anywhere?

No. The secret is processed entirely in your browser to generate the code.

What is a TOTP code?
