Generate a 2FA code

Paste a Base32 secret (setup key) and get the same 6-digit TOTP code that Google Authenticator would show. The code follows the RFC 6238 standard and refreshes every 30 seconds. Everything is processed on your own machine.

Secret key (Base32)

Paste the 2FA setup key the service gave you when you turned on two-factor authentication. All the maths happens in your browser — your key is never sent anywhere.

No key yet

Enter a Base32 secret in the box on the left to start generating 6-digit TOTP codes.

Security tip

Your secret key never leaves the browser — the tool sends nothing to a server and stores no keys.
Only use this tool for accounts you actually own. Don't enter someone else's 2FA key.
If the code isn't accepted, check that your computer's clock is correct — TOTP depends on the time.
