Is the invitation feature necessary if the user can login with external login providers, as portal automatically creates contact. I don't see any difference between the login credentials and contact association with or without invitation code feature. Please elaborate, I'm new to portals. I have an app where user can login with Open ID provider. Do I need Invitation feature? We already have a web app with users provisioned, we are migrating to Powerapps portal. The new app will be provisioned to the same existing domain url. Open ID authentication will automatically create contacts. I don't find any reason on why we need invitation? Does it limit user in any way?
