4. Select which applications will allow Facebook SSO.
5. Select Save.

Users will now see Facebook as an option to sign up and sign in to the selected applications.

Facebook does not require an email for sign up, but Kinde does. So if a user signs up with Facebook and an email is not detected, we will ask for one.

The user only needs to provide their email once, then they can sign in via Facebook without disruption.

If the email they provide is already detected in Kinde, we will automatically link the accounts so as not to duplicate.
