When was the last time you actually signed into Facebook? The social network is such an essential part of our lives that we habitually leave our accounts signed in on trusted computers. For those who try to take a break, Facebook does everything it can to make it easier to come back. The Facebook mobile apps have a Profile Picture login feature that lets you log in to the Facebook app by just tapping on your profile picture. This feature is meant to be used when you log out of the app or uninstall it, and need to log in again. It isn’t automatically enabled and you have to give Facebook explicit permission to enable it. If you have enabled it and are having second thoughts, disabling it is easy enough. Here’s how.
Profile Picture Login makes logging in much faster after you’ve logged out. If you reset a device to factory settings or wipe, it will likely remove the device from your Facebook account. It doesn’t serve as much of a security feature. If you have profile picture login enabled, and you sign out of the Facebook app, signing back in takes only a tap. You might want to go with the 4 digit PIN option instead if you’re looking for something more secure.
