Users receive notifications when their account is logged into from a new device or location

1. Click Login Alerts

2. Select Get notifications

3. Select the type of notifications you want to receive and click Save Changes. Email notices will be sent to your email on file with Facebook and a text message will be sent to the mobile phone on file with Facebook.

4. If you opt for text message notification and a mobile phone number has not already been associated with your Facebook profile, you will be asked for it. Enter a mobile phone number and click Continue. Facebook will forward a text message to that mobile phone for verification.

5. Check the phone for a message, enter the confirmation code, and click Confirm. The confirmation code might be rejected if too much time has elapsed after the text message was sent. Facebook is very general about the maximum allowable time.
