To update your last name on your Microsoft Learn profile, you will need to log in to your profile and follow these steps:
- Select the profile icon in the top right corner.
- Select Settings.
- Under Personal info, you can update your legal name.
- Follow the instructions for updating your Legal Name.
- If you see messaging asking you to contact Certification Support, please follow the link and file a ticket with the Credentials Support team.
Please note that your legal name must match the name on the government-issued ID you'll present at your exam appointment. If you've already registered for an exam, changing it requires Microsoft support approval.
