Frequently Asked Questions

Is this compatible with Google Authenticator?

Yes, this tool uses the same TOTP algorithm (RFC 6238) as Google Authenticator, Authy, and other authenticator apps.

Is my secret key safe?

Yes, all processing happens in your browser. Your secret key is never sent to any server.

Why does my 2FA code not work?

TOTP codes are time-based, so your device clock must be accurate. If the code fails, check that your system time is synced correctly. Also ensure you're using the correct secret key.

What is a TOTP secret key?

A TOTP secret key is a Base32-encoded string provided by the service when you set up 2FA. It's usually shown as a QR code or a text string you can copy manually.

Can I use this as a backup for my phone authenticator?

Yes. If you have the secret key saved, you can use this tool to generate codes whenever you don't have access to your phone. Always store your secret keys securely.
