Facebook Login is a fast and convenient way for people to create accounts and log into your app across multiple platforms. It's available on iOS, Android, Web, desktop apps and devices such as Smart TVs and Internet of Things objects.

You can use Facebook Login simply for authentication or for both authentication and data access.

Skyscanner, an app for finding flights, hotels, and car rentals, has experienced a 100% increase in the number of people using Facebook Login to access the app.

Facebook Login supports
many permissions which determine which information people choose to share with your app. This means you have precise control over what you request and people have precise control over what they choose to approve.
We want to ensure the tens of millions of people who use Facebook Login every day have a safe, reliable and consistent experience. App Review helps determine if apps that are requesting access to detailed account information have built great experiences.
Our App Review process is designed to be fast and lightweight. Our review team actually uses your app and will provide guidance and feedback to ensure you're meeting our Platform Policies.
Apps may ask for the following two permissions from any person without submitting for review by Facebook:
To ask for any other permission, your app will need to be reviewed by Facebook before these permission become visible in the Login Dialog to the public who're logging into your app with Facebook.
However, to help you develop your Facebook Login experience, anyone listed in the Roles section of your app's dashboard will be able to grant any valid permission without approval from Facebook.

Facebook gives people control of their data by providing a way for people to request your app to delete the data it has from Facebook about them. To respond to such a request, implement a data deletion callback.
