How do I change a user's email address if my enterprise has SSO enabled?

When you enable SSO for your enterprise, the identity provider (IdP) that you integrate with is the authority for user information such as email address. If you need to update a user's email address, simply update it in the IdP, and the change will flow naturally into QA.

For example, if you have set up your account to use SSO with Okta, then your users use their regular Okta credentials to log in to QA. After you update the user's email address in Okta, the next time the user tries to log in to QA, QA looks for the new email address in Okta and finds it there. Because Okta knows the new email address, QA knows to let the user log in.
