Step by Step How to Authenticating to Azure by using Windows PowerShell Certificate Based
After you install the Azure PowerShell module, you need to connect it to the Azure subscriptions that you want to manage with it. You can take two approaches to accomplish this: Azure AD Authentication and certificate-based authentication.
Most tools for managing Azure support Azure AD Authentication, and it is the recommended authentication model. However, in some cases, it might be more appropriate to authenticate by using
certificates. Examples of where certificate-based authentication is appropriate include older tools that do not support Azure AD Authentication and Windows PowerShell scripts that will run for long periods of time in which an authentication token might expire.
