A security key is a physical device you can take with you that acts as a key to accounts with sensitive information. In the digital age, it's nice to have something tangible that works the old-fashioned way instead of having to rely on memory or have your iPhone on you at all times for two-factor authentication. If you already own a security key and are ready to secure your Facebook account, here's how to set up a security key.

If you have a security key already, then you know how important it is to have something a bit stronger than just a password to protect your most sensitive accounts. However, if this is your first time hearing about security keys, the most important thing to understand is that the security key acts as a second step when signing into accounts you've linked it to.

Once you've associated your accounts with the security key, you will need both your password and the key itself in order to log in to your accounts. This keeps your accounts secure and protected from hackers who may have your password. However, if you use a security key, they will not be able to hack your account unless they have the security key.
