# Managing users, roles & SSO

Tenant administrators manage users from **Settings**. Seal supports four user roles with distinct permission sets, an invite-based flow for adding team members, and SAML single sign-on for organizations that use it.

* [User roles](/new-documentation/new-docs/users-and-sso/user-roles.md): the four roles (Admin, Sealer, Collaborator, Watcher) and the permission matrix.
* [Inviting and managing users](/new-documentation/new-docs/users-and-sso/inviting-users.md): the invite flow, role changes, and revoking access.
* [SSO and SAML](/new-documentation/new-docs/users-and-sso/sso-and-saml.md): connecting your identity provider through the authentication portal.
