Facebook Login gives you a fast and easy way to sign in to your favorite apps. You can skip entering in long registration forms on mobile and the need to remember yet another username and password by logging in through Facebook with a few simple taps.

Updates to Facebook Login

Although Facebook Login is widely used, we understand people’s concerns about apps posting on their Timeline or to their friends. For the past several months, we’ve been rolling out a new version of Facebook Login on mobile to address these concerns.

Don’t want to share your music playlist or workout routine with friends? You can choose to skip sharing altogether. Clearly separating sharing means people can decide whether they only want to use Facebook Login for fast registration without also sharing back to Facebook. If you want to share later, you still can.

In addition to separating sharing requests, we’ve also made Facebook Login load up to 31% faster on mobile***. Our goal is to get you to connect with your favorite apps as quickly and easily as possible.

We’ve been working directly with popular mobile apps to help them create great Facebook Login experiences. The recent changes to Login are just the beginning of more improvements you’ll see as we continue working to provide useful services for developers that are easy for users to understand.
