Privacy Policy for Sign In With Facebook Button

Facebook Connect or "Login with Facebook" is the button that allows Facebook users to use their accounts to log in at or create accounts with other websites.

Login with Facebook works with over 15,000 other websites and allows for increased and more efficient interactivity between users and websites.

For example, if you use Facebook Connect to connect to a third-party website and leave a comment on a blog post on that third-party website, you can set up your Facebook account to publish your comment automatically to your "wall" or newsfeed so all of your Facebook friends can interact with it.

Facebook Connect also saves people time by not requiring users to have to re-enter personal information and create accounts at all of their favorite websites.

By clicking the Login with Facebook button or the Signup with Facebook button, all of your information will automatically be transferred to the third-party website and an account will be created automatically for you.

Examples of Facebook Connect button

This kind of functionality is commonly used both on websites and mobile apps and can be found across the board, from games and entertainment apps and websites to business and productivity apps and websites.

According to Facebook's Statement of Rights and Responsibilities, if you develop a Facebook app or sign up to use a Facebook app such as Facebook Connect, you must adhere to Platform Policy of Facebook:

Special provisions clause in Facebook Statement of Rights

This Platform Policy includes a section called "Give people control" that lists a number of requirements, including the requirement that a Privacy Policy must be publicly provided and be made easily accessible:

Facebook Platform Policy: Give People Control

Not only must the agreement be publicly provided and be made easily accessible, but it must also:

  • Explain what data you are collecting, and
  • How you will use that data

This means you must let users know what data you are collecting when a user chooses to log into your website or mobile app via the Facebook Connect button, and how you will use that data.

Here are a few examples of websites that use Facebook Connect and the relevant clauses in their Privacy Policies that inform users about what data they might collect when an account is set up via Facebook Connect.

The Privacy Policy of Fitbit reflects this, and provides users with information about what information will be collected if a user signs up via Facebook.

Fitbit states that users will "have the option to create your Fitbit account using a different credential like your Facebook or Google+" and then goes on to clarify that basic information from that account, like your name, profile picture, and friend list" will be collected if permission is granted by the user.

Users are also informed that permission can be revoked at any time and that the purpose of accessing the contact/friends list is for the purpose of letting Fitbit and Facebook users identify which of their Facebook friends are also Fitbit users.
