We would like to use Azure client credentials flow to do authentication for our service accounts. The thing is our service accounts are just regular users in Azure AD. They are not registered apps. The way our company sets up Azure makes it very heavy to register apps, so we would like to avoid it. So the question is, can we use client credentials flow for regular users in Azure? We need this as in our CI/CD we cannot popup a browser and let users do device-based authentication. We need the user to be able to authenticate in an automated way.
