Social sign-on
Social sign-on, also known as social login, enables customers to authenticate with your storefront through a social network provider, such as Facebook, Google, or Apple. When a customer uses social sign-on, the storefront sends a request to the social network provider, which attempts to verify the customer's identity or leads a new customer through a registration process. The social network provider returns the results of the authentication to the storefront.
