A small tip that makes a big difference. Keep your device's date and time set automatically. TOTP codes depend on the correct time.
Try it nowWhich 2FA keys can I use?
Use standard time-based authenticator (TOTP) setup keys in Base32, HEX or Base64, or an otpauth://totp link. Formatting spaces, lowercase Base32 and Base64URL are supported. The tool supports SHA-1, SHA-256 and SHA-512, 6–8 digits, and refresh periods from 15–120 seconds. SMS and email codes, passkeys, push approvals, HOTP counter keys and encrypted or migration exports use other methods; use the service’s original TOTP setup key.
What is a 2FA secret key?
It is the reusable setup key your service provides when you enable an authenticator app. It usually contains letters A–Z and numbers 2–7. It is different from your account password, a one-time code or a recovery code. Keep it private: anyone with the key can generate your codes.
Are my secret keys saved or shared?
Code generation happens in your browser. With Remember on this device enabled, valid keys are automatically saved in this browser and restored on your next visit. They are not sent to our servers. Turn remembering off or use Forget saved keys to remove them. Use remembering only on a browser you trust.
Will my keys still be here after 60 or 70 days?
There is no automatic expiry for remembered keys. They can stay available for 70 days and longer, as long as you return using the same browser profile and website address and the browser retains its site data. Clearing browser data, private browsing or browser cleanup can remove them. Saved keys do not sync to other devices or domains.
Why is my code being rejected?
First, enable automatic date and time on your device. Copy the full setup key for the correct account and use a fresh code before it expires. Most services use SHA-1, 6 digits and 30 seconds; check the service's settings if yours differ. A wrong key or an account that has reset 2FA will need the correct setup key.
Does it work with Google, Facebook and other services?
It works with accounts using standard time-based one-time passwords (TOTP). The key and settings must match the service. It does not generate SMS codes, approve push notifications, replace passkeys or bypass account security. 2famh is independent of the platforms named here.
Can I use it without an internet connection?
After this page has fully loaded, code generation can continue without a connection while the page stays open. An accurate device clock is still required. Reopening or reloading the website needs an internet connection.
I don't have my setup key. Can you recover it?
No. This tool requires an existing setup key. Use your service's official recovery process or a saved recovery code if you have lost access. Store your setup keys and recovery codes securely, such as in an encrypted password manager.
