About the 2FA Generator
What the 2FA Generator does
Paste your 2FA secret keys and this page shows the current six-digit code for each one, with a countdown to the next rotation. The code is calculated inside your own browser — the secrets never leave the page.
How to use the 2FA TOTP Generator
- 1.Paste one secret key per line, or an otpauth:// link.
- 2.Press Generate Codes; every account gets its own card with a live countdown.
- 3.Click a card to copy its code before it rotates.
Frequently asked questions(4)
- Are my secret keys uploaded?
- No. TOTP codes are generated locally in your browser, so the keys stay on your device. That is also why the tool keeps working on a weak connection.
- Which 2FA apps does this replace?
- Any standard time-based one-time password. Google Authenticator, Authy, Microsoft Authenticator and the 2FA behind Discord, Facebook and Instagram all produce the same six-digit code from the same secret key, so a key from any of them works here.
- Does it work for Steam Guard?
- No. Steam Guard codes are not standard six-digit TOTP, so this generator cannot produce them. Saying no is better than handing you a code that will be rejected.
- Which kind of 2FA is supported?
- Standard time-based one-time passwords — six digits, 30-second period — which is the format Google Authenticator, Authy and most other apps use.
