How to use: Enter your 2FA secret key in the textarea above and click "Generate 2FA Codes". The verification code will be generated and displayed. You must enter this code to log in before it expires, otherwise you'll need to generate a new one.

Multiple 2FA Keys: Our tool supports generating codes for multiple 2FA secrets at once. Simply enter each 2FA secret on a new line. This is useful when you need to access multiple accounts secured with 2FA.

Local Storage Security:

  • Your keys are stored only on your device and never sent to our servers
  • Keys can be accessed again when you revisit the site
  • You can disable storage completely using the "Save keys locally" toggle
  • You can clear all saved keys at any time
  • Anyone with access to your device could potentially see your saved keys

URL Method: You can also append the 2FA secret to the URL. This makes it easier to quickly access your 2FA code.

Frequently Asked Questions

Find answers to common questions about 2FA, two-factor authentication, and how to use our 2FA code generator tool.

What is 2FA or two-factor authentication?
Two-factor authentication (2FA) is a security method that requires two different forms of identification to access an account. This typically includes something you know (like a password) and something you have (like a smartphone that generates a one-time code). It significantly increases account security by adding an extra layer of protection beyond just a password.
How does the 2FA code generator work?
Our 2FA code generator creates time-based one-time passwords (TOTP) based on the secret key you provide. It uses the HMAC-SHA1 algorithm to generate a 6-digit code that changes every 30 seconds. These codes are identical to those generated by authenticator apps like Google Authenticator, Microsoft Authenticator, or Authy.
Where can I find my 2FA secret key?
When setting up 2FA on a website or service, you'll typically be shown a QR code along with a secret key (a string of letters and numbers). You can use either the QR code with an authenticator app or manually enter the secret key into our tool. If you've already set up 2FA but didn't save the key, you may need to disable and re-enable 2FA on that service to get a new secret key.
Is it safe to enter my 2FA secret keys on this website?
We take security seriously. All code generation happens directly in your browser - your secret keys are never sent to our servers. For maximum security, we recommend using the "Save Locally" feature which stores your keys in your browser's local storage rather than on our servers. However, for truly sensitive accounts, we recommend using dedicated authenticator apps like Google Authenticator or Authy.
How are my 2FA keys stored when I use this tool?
By default, your 2FA keys are stored in your browser's local storage, which means they remain on your device only and are never transmitted to our servers. You can disable this storage feature using the "Save keys locally" toggle if you prefer not to save them at all. Local storage provides convenience as your keys will be available when you return to the site, but remember that anyone with access to your device could potentially see your saved keys.
Can I save multiple 2FA codes?
Yes! Our tool allows you to enter multiple 2FA secret keys separated by new lines. Each key will generate its own code. This makes it convenient to manage multiple 2FA codes in one place without switching between different apps.
What if I lose access to my 2FA codes?
Most services provide backup or recovery codes when you set up 2FA. Keep these codes in a secure location. If you've lost access to your 2FA codes and don't have backup codes, you'll need to contact the service's support team to regain access to your account, which usually requires identity verification.
