What authentication option is available under the admin settings aside from local, remote, and 2FA?

The authentication option available under the admin settings aside from local, remote, and 2FA is SAML SSO (Security Assertion Markup Language Single Sign-On). SAML SSO is a widely used standard that allows users to authenticate once and gain access to multiple applications without the need for multiple sets of credentials. This is particularly beneficial in enterprise environments where seamless access to various services and applications is critical.

Implementing SAML SSO in FortiAnalyzer enhances security and user experience by enabling single sign-on through identity providers. This means users can initiate the authentication process via a familiar identity provider, which manages the credentials, thereby reducing the administrative overhead of managing local user accounts and providing a streamlined login experience.

Other methods like LDAP, RADIUS, and OAuth 2.0 are popular authentication mechanisms as well; however, SAML SSO stands out in its ability to provide a single sign-on capability that is particularly advantageous in environments where integration with other web-based applications is needed.
