Hi @Miguel ,
Thanks for reaching out.
If I understood correctly, it seems you want to configure custom domain in the B2C URL which will change the default one my-tenant.b2clogin.com to myapp.com
This can be achieved by enabling custom domain in Azure AD B2C. B2C custom domain functionality works with Azure Front Door.
Refer to configure custom domain in Azure AD B2C: https://learn.microsoft.com/en-us/azure/active-directory-b2c/custom-domain?pivots=b2c-custom-policy
Here , app registration endpoints specify the default domain of B2C which further invokes the front door to resolve custom domain name.
Hope this will help.
Thanks,
Shweta
