# Social Authentication
> Social Authentication, often referred to as 'social login,' is a form of single sign-on (SSO) that allows users to authenticate themselves on various platforms using their existing credentials from social networking services. It acts as an integration layer between a service provider and an identity provider to simplify the registration and login processes.
