# Two-factor authentication (2FA)

## How do I enable 2FA?

1. Make sure you have an authentication app that supports QR codes installed on your mobile device. We recommend either of these:
   1. Microsoft Authenticator ([iOS](https://apps.apple.com/us/app/microsoft-authenticator/id983156458)) ([Android](https://play.google.com/store/apps/details?id=com.azure.authenticator))
   2. Google Authenticator ([iOS](https://apps.apple.com/us/app/google-authenticator/id388497605)) ([Android](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2))
2. Go to your account settings page by clicking on your username in the top-right corner and selecting "Settings"
3. Find the "Two-factor authentication" setting and click on Enable
4. Continue by signing out or clicking the "Complete now" button
5. Sign in with your username and password
6. After signing in, you will be presented with a QR code
7. Open your authentication app on your mobile device and scan it or enter the code manually
8. Your authentication app will now generate a new code every minute or so
9. Enter this code in Rulecube
10. You have now enabled 2FA!
