How to Log into XMS with PIV-Derived Credentials

This job aid assists users on how to log into XMS on a mobile device using their PIV-derived credentials, including the first-time user account registration process.

XMS currently only supports PIV-derived credentials with an Authentication Assurance Level (AAL) of three (3). If you are not sure of your credential’s AAL, contact your issuing agency for additional help.

  1. From the XMS login page (https://xms.hhs.gov), click the "PIV Derived" button. For quick and easy access to your applications, add this page to your browser favorites or create a desktop shortcut.

    NOTE: A valid and active PIV-derived certificate must already be installed on the mobile device before you can login.

    NOTE 1: If you are having trouble identifying the correct certificate from the list presented to you in the pop-up window, please contact your local IT helpdesk.

    NOTE 2: If your PIV-derived credentials have already been registered in XMS you do not need to complete steps 3 - 4. Continue to step 5.
