1. Open the Facebook app or head to the Facebook website in your phone's web browser.

2. Enter the phone number or email associated with your Facebook account, and then the password.

If you have two-factor authentication set up, you might be asked to enter a security code.

Can you tell if someone tries to log into your Facebook?

If you have two-factor authentication set up on Facebook, you will receive a confirmation code to your phone or email when there is a login attempt on your account. If you did not recently try to log in, you can assume it was someone else.

You can also turn on login alerts by going to Settings > Account Center > Passwords and Security > Security Checkup > Turn on Login alerts on Facebook desktop. You can choose whether you want to receive a notification on Facebook or via email.
