Social login is the ability to present the option for a site visitor to sign in with their social accounts like Facebook, Twitter, LinkedIn and etc. AEM supports OOTB Facebook and Twitter Social logins but Google login is not supported OOTB and need to build custom Provider to support the log in flow for websites.
AEM internally uses the scribejava module to support the Social login flows, scribejava supports multiple providers and both OAuth 1.0 and OAuth 2.0 protocols.
