How do I add a security key to my Facebook account?

In order to add a security key to your account, you’ll first need to purchase your own third party Universal 2nd Factor (U2F) or FIDO2 security key. Some types of keys can be used by inserting them into a USB or lightning port. Other types of keys can be used by holding them near your computer or mobile device. Before purchasing, make sure that your security key is compatible with the browser and the device that you use to login to your account. After you add a key to your account, you can then use that key to login.
To add a security key on your desktop, you'll need to be using the latest version of Chrome, Opera, Firefox, Edge, or Safari. You’ll need to have a Bluetooth, USB, or NFC security key. You’ll need to ensure that your computer is compatible with your security key.
To add a security key:
  1. Go to your Security and login settings.
  2. Scroll down to Use two-factor authentication and click Edit. You may be asked to re-enter your Facebook password at this point.
  3. Click Use security key.
  4. Click Register security key then follow the on-screen instructions. If you do not see the Register Security Key option, you may need to update your browser.
Once you’ve successfully added a security key to your account, you can start using it when you log in. Learn more about how to log in with your security key.
