How to Use a Security Key to Lock Down Facebook

By - Source: Toms IT Pro

Passwords aren't enough to protect your data. As an IT professional, you know that. But, did you know you can add a physical security key to your Facebook account to lock it down? 

The social network recently added a new security feature called login approvals. It requires a Universal 2nd Factor (U2F) compatible USB key, supported by the FIDO Alliance. Right now that limits your available options to a few keys, such as those by Yubico. U2F keys like these can also be used to secure other passwords such as  Google, Dropbox, Salesforce and GitHub.

You use the key when logging into Facebook from a new computer or mobile device. It only works with up-to-date versions of Chrome or Opera, and it doesn't work with the Facebook app for Android. But for those you can always set up two-factor authentication having a code sent to your phone. 

Here's how to get a physical security key set up. 

1. Log into Facebook online. Then, click the lock/hamburger menu on the top right of the page. 

2. Click See More Settings.

3. Click Security. 

4. Click Edit next to Login Approvals. 

5. Click Add Key next to Security Keys.
