2FA tool

Enter the two-factor secret used by Google Authenticator or another authenticator app to get a login code in your browser. No app installation needed.

Your login website provides this secret when you enable two-factor authentication. It is not your login password or an SMS code.

Advanced settingsSHA1 · 6 digits · 30 seconds

Usually no changes are needed. Match these settings to your account's two-factor authentication settings.

After generating a code, we try to copy it automatically. Paste it before the countdown ends.

Current verification code

Enter your secret, then click "Get verification code".

Codes are calculated in your browser. Your secret is never uploaded and is not saved by default. If you enable history, it is saved only in this browser.

Add to your mobile authenticator

Scan with Google Authenticator or another mobile authenticator to add the same secret and view verification codes.

Secret history

Off by default. Enabling saves secrets in this browser; turning it off deletes the saved history.

How to use

  • Use the secret from the account you want to sign in to. Random text cannot replace that account's secret.
  • Paste the code into the website before it expires. A new code is generated automatically when it expires.
How can I check that the code is correct?

Load the public demo secret and generate its QR code. Scan it with Google Authenticator, then click "Get verification code" and compare the codes at the same time with matching settings.

If the codes differ, enable automatic time on both devices and check the algorithm, code length and period. The demo only checks code generation; it cannot verify a real account login.
