How do I add users to my TestRail instance?

You can add and invite additional users to your TestRail instance, including team members and customers. To add and invite additional users, simply select Administration > Users & Roles from your TestRail account. You can either add additional users one by one via the Add User button, or you can add many users at once via the Add Multiple Users button. The Enterprise edition of TestRail offers support for Single Sign-On (SS0) for identity providers such as Okta and Azure, using the SAML 2.0 protocol.
