Login Facebook with Your Username
Back in June, Facebook introduced vanity URLs for all its users where they could have a personalized URL for their profile pages which would be much easier to share among friends.
Today, Facebook announced that now you could even login to your Facebook account using your username.
This new feature works from the web and mobile versions both. So now, web users get two options to login with (email and username) and mobile users have three options (email, mobile number and username) for logging into Facebook.
The email login is still there and won’t stop working as many users still haven’t got a username for their accounts.
