Providers Must Have a Valid Email Address on Record to Access TMHP Applications Through TMHP IAMOnline

Last updated on

On August 3, 2026, the Texas Medicaid & Healthcare Partnership (TMHP) will transition the My Account portal application to TMHP IAMOnline. Providers must be able to access TMHP IAMOnline to use My Account.

Providers must verify by July 30, 2026, that their My Account profile is active and their email address is valid. This will ensure that they can receive the TMHP IAMOnline activation email so that they can access TMHP IAMOnline.

If providers have an old or invalid email address on record, they must update the address immediately to avoid any interruption in access.

Important: July 30, 2026, will be the last day for providers to update their email address in My Account before it transitions to TMHP IAMOnline.

Updating Email Addresses After the Deadline

Providers that are not able to log in to TMHP IAMOnline after July 30, 2026, due to an outdated email address, must complete the TMHP Portal Change Request Form to activate their TMHP IAMOnline account and access TMHP applications. Completing the manual email update form may be time-consuming and cause delays for providers.

For more information about the My Account transition to TMHP IAMOnline, refer to the article titled “New Login Process for All Texas Medicaid Providers Through TMHP IAMOnline and Provider MFA Registration for Transition Release 3” that was posted on June 12, 2026.
