What are login approvals? How do I turn this setting on?

Login approvals are an extra security feature similar to login notifications, but with an extra security step. If you turn on login approvals, you'll be asked to enter a special login code each time you try to access your Facebook account from a new computer or mobile phone. After you log in, you'll have the option to give that device a name and save it to your account. You won't have to enter a code when you log into any of these recognized devices.

To turn on Login Approvals:

1. Go to your Security Settings page ( > Account Settings > Security)
2. Click on the Login Approvals section
3. Check the box and save your changes

If you use the Facebook app on your smartphone, you can get your login codes instantly instead of waiting for a text (SMS) message. Learn more.

Note:

• You have 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, or learn more.
• If you haven't named this computer, you'll be asked to do so when you turn on login approvals. Don't click the Save this device option if you're using a computer that other people use (ex: a library computer).
• After you turn on login approvals, we need to be able to remember your computer and browser info 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.
