hello 녕은 윤,

To change the sign-in account to an account with a custom domain:

1. Sign in Azure portal: Go to portal.azure.com
2. Microsoft Entra ID: In the azure portal, search Entra ID.
3. Add a custom domain: Search "Domain names" in the Entra portal > Click on "Add custom domain." > Enter the new domain name (e.g. abc.com) and click "Add domain."
4. Verify the domain (you need to own the domain): Follow instructions to verify that you own the domain - by adding a TXT record to your domain's DNS settings
5. Set the new domain as primary: Once verified, you can set the new domain as the primary domain. In the Entra portal: Search Domain names> Click on the Domain you verified> Make primary
6. Create a new user using the new domain
7. Ensure the user has the relevant RBAC in Azure (Owner, Contributor etc)

To create an onmicrosoft.com domain, follow these instructions.
