1. SAML single sign-on authentication involves a service provider and an identity provider. In this scenario, the service provider is your Member Portal, which was— created via Zoho Sites. When you've enabled SAML, the end-user management and authentication are handled through your company's identity provider (IDP). An end user who requests access to your website via your member portal will be redirected to your identity provider for authentication. 
   

1. The identity provider authenticates the end user and in return, generates an authentication assertion in return. This indicates that a user has been authenticated. Upon receiving the assertion, the end user is redirected back to your website and signed in seamlessly. 
   

1. As a single point of authentication that happens with your trusted identity provider, SAML ensures that your end-user credentials are secure within your company's firewall boundary.
