Two-factor authentication
Make your account more secure using two-factor authentication (2FA). 2FA means that there are two different factors (your credentials and an additional verification code) needed to authenticate you as a user when logging into your account.
You must have an authenticator app installed on your mobile device.
There are many authenticator apps available (e.g. Google Authenticator, Authy, Microsoft Authenticator, or 1password). We will use the Google Authenticator app in our example.
- Go to your profile settings, and open the Two-Factor Auth tab.
- Click the Enable button to display the Enable Two-Factor Authentication dialog with QR code.
- In the Google Authenticator app, tap Scan a QR code.
Note
Permissions may need to be granted to allow the app to scan the QR code using your device's camera.
- Enter the six-digit verification code generated by the Google Authenticator app and your password in the Enable Two-Factor Authentication dialog box, and click Enable.
Important
Save the provided One-time passwords in a safe place (not on your mobile device). You can use these one-time passwords to recover access to your account if your mobile device has been stolen or lost, or if the authenticator mobile app has been removed from your phone.
- Click the Download codes button to download the TXT file containing all your one-time passwords.
After signing out, you can now log in using 2FA.
- Go to the login page.
- Enter your credentials, and click Sign In (or sign in using Google, Facebook, or GitHub).
- Open the authenticator app (e.g. Google Authenticator) on your mobile device to get the verification code.
- Enter the verification code provided by the authenticator mobile app in the Two-Factor Authentication Code field, and click Sign In.
Note
If you have lost your mobile device, or accidentally deleted the authenticator app, you can use one of the one-time passwords you have stored in a safe place after enabling the 2FA on your account (step 6 in the Enabling Two-Factor Authentication section above).
- Log in to your account. If you don't have access to your authenticator app, use one of the one-time passwords you have stored in a safe place after enabling the 2FA on your account (step 6 in the Enabling Two-Factor Authentication section above).
- Click on your profile name (bottom-left corner), then click Profile, then click the Two-Factor Auth tab.
- Click the Disable button, enter the verification code generated by your authenticator app on your mobile device, enter your password, and click Disable.
Two-factor authentication is now disabled on your account.
If you want to use another app for the two-factor authentication or another phone, you first need to disable the two-factor authentication on your account using your current authenticator app or one-time password.
- Disable the two-factor authentication on your account (see above).
- Install another authenticator app on your mobile device (or the same app on the new mobile device).
- Enable the two-factor authentication on your account (see above) using your newly installed authenticator app.
