Login approvals are a security feature similar to login alerts, but with an extra security step. If you turn on login approvals, you'll be asked to enter a special security code each time you try to access your Facebook account from a new computer, phone or browser.

To turn on login approvals:

1. Go to your Security Settings
2. Click the Login Approvals section
3. Check the box and click Save Changes

After you turn on login approvals:

• If you haven't saved the device (ex: computer) or browser you're using, you'll be asked to do so when you turn on login approvals. This way you won't have to enter a code when you log in from any of your recognized devices or browsers. Don't click Save this browser if you're using a public computer (ex: a library computer).
• We need to be able to remember your computer and browser information so we can recognize it next time you log in. Some browser features block this. If you've turned on private browsing or set up your browser to clear your history every time it closes, you might have to enter a code every time you log in. Learn more.

Note: You need to have a mobile phone number listed on your account to turn on login approvals. You can add one to your account when you turn on login approvals.
