External ID

Full Title

External User Management System (XMS) is used by the U.S. Department of Health & Human Services (HHS). XMS is a cloud-based identity federation broker that provides a unified digital identity experience for various HHS mission areas1.

If you need to log in or access specific applications, you can do so through the XMS login page2. For detailed instructions on logging in with Login.gov credentials, you can refer to the HHS job aid3.

As soon as NIST described External User Management Systems, companies, like Microsoft, started describing anything produced by their Directory Services, like Entra, as External IDs.
