Moving from MiWAM to MiUI

As part of the transition to MiUI, UIA will attempt to convert all Employer–TPA relationships that currently exist in MiWAM into MiUI, including WOTC TPAs. The exception is when an employer has two or more TPAs assigned in MiWAM. In this case, the employer will not be added to the TPA’s record and must grant permission to that TPA in MiUI. The employer will need the TPA’s new MiUI TPA ID to complete this action. TPAs with the proper authorization can also associate themselves with an employer outside of the Automatic Assignment process.

Although Employer–TPA relationships are being brought over from MiWAM, the specific roles previously assigned to TPAs are not. Details on which TPAs will receive which roles can be found in the TPA Assignment & Association Quick Reference Guide on MiUI University.

Yes. If you are an employer who is also a TPA in MiWAM, or a TPA who is also an employer, you will have two Activation Codes.

If you are both an employer and a TPA, you will need to log in using your Master access security to see both activation codes on your homepage.

If you are missing employers or need updates to your role assignment, you can use the communication template to help you inform your employers.

Please make sure you share your TPA ID, role(s), and start service date with your employers. Employers will need to be the ones to log in and assign you as their TPA.

You will only see the MiUI Activation Code tab in MiWAM if you have the Master access security role. If you have the Limited access security role, you will not see the MiUI Activation Code tab and will need to have the Master access security role user initiate the existing Employer or TPA account.

Contact the Office of Employer Ombudsman at 1-855-484-2636, Option 4 for assistance.

If you are not able to access your MiWAM account, please use the "Forgot your Username?" or "Forgot your Password?" to retrieve your MiWAM username and/or password.

If you are not able to retrieve your MiWAM account information, please email MiWAMSupport@michigan.gov with an overview of the access issues you’re experiencing and provide a new email address so that we are able to provide you with your MiUI Activation Code. 

Account activation refers to the process of adding a new user to an existing account and granting access to that account after Go Live.

Account initiation is the one-time process to access an existing MiWAM account that was transferred to MiUI at Go Live on February 23, 2026.

The MiUI Activation Code found in MiWAM is used to initiate your MiUI account. It is used for existing accounts that have been transitioned from MiWAM to MiUI. The code is located in the MiUI Activation Code tab of your MiWAM account.

The Activation Code for new users is required when users are added to MiUI and assigned within an employer or TPA account. New users will receive an email with an Activation Code and steps to follow to activate their account.

New users will require:

• Their own MiLogin for Business account
• The same credentials including:
  • Employer Account Number (EAN)
  • FEIN
  • SSN (TPAs only)

The Office of Employer Ombudsman (OEO) can help initiate your MiUI account. If you have questions, call OEO at 1-855-484-2636, then select Option 4.

• Federal Employer Account Number (FEIN).
• MiUI Activation Code from the Activate User Profile email.

TPAs will need:
