Is it safe to use an online 2FA generator?

Yes, absolutely. 2fa.bd processes your secret key using client-side JavaScript, so the key never leaves your device. It is just as secure as using a hardware device or a mobile app.

Can I use 2fa.bd instead of Google Authenticator?

Yes! 2fa.bd uses the exact same TOTP (Time-based One-Time Password) algorithm as Google Authenticator, Microsoft Authenticator, and Authy. It is fully compatible with any platform that supports standard 2FA setups.

What happens if the 2FA code expires?

Standard 2FA codes refresh every 30 seconds. If your code is rejected, simply click the Generate button again on 2fa.bd to get a fresh, synchronized code.

What is Two-Factor Authentication (2FA)?

Two-Factor Authentication (2FA) is an extra layer of security for your online accounts. Besides your password, it requires a second verification step — usually a 6-digit code generated by an authenticator app or tool like 2fa.bd.

Do you store my secret keys?

No, 2fa.bd never stores your secret keys. All code generation happens entirely in your browser using JavaScript. Your keys are never sent to any server.

All code generation occurs entirely within the user’s web browser using client-side JavaScript. We do not transmit, receive, store, or process any secret keys on our servers.
