We will only take a look at the type of Application. The docs do also describe the three different types of service principals. This basically means that a service principal is defining which access and permission an application that tries to access a resource within Azure has. This enables core features such as authentication of the user/application during sign-in, and authorization during resource access. The security principal defines the access policy and permissions for the user/application in the Azure AD tenant. This requirement is true for both users (user principal) and applications (service principal).

To access resources that are secured by an Azure AD tenant, the entity that requires access must be represented by a security principal. The Microsoft docs do describe a Service Principal very well. Backgroundįirst of all, we have to talk about what a Service Principal is and why we should use it. This blog post intends to explain this common request.

Every now and then I get the question on how to setup a Service principal in Power automate.
