What is how to implement external user logins for a web application and how does it work?

External user logins for a web application allow users to authenticate using third-party services such as Google, Facebook, or enterprise SSO (Single Sign-On) solutions. This is typically implemented using OAuth, OpenID Connect, or SAML authentication protocols. Many businesses integrate authentication systems with low-code software to simplify access management without requiring custom development.
