M365 Changelog: Certificate based Authentication for Security and Compliance Center PowerShell

MC316448 – With this update, which will improve the security of your tenant, Security & Compliance PowerShell will enable configuration of certificate-based authentication to allow unattended App-only access. 

When this will happen:

Rollout will begin in mid-February and is expected to be complete by early March.

How this will affect your organization:

If your organization is currently using “Basic authentication” for application access, you will need to migrate to certificate-based authentication prior to mid-February.

What you need to do to prepare:

To migrate to certificate-based authentication, follow these steps:

• Step 1: Register the application in Azure AD
• Step 2: Assign API permissions to the application
• Step 3: Generate a self-signed certificate
• Step 4: Attach the certificate to the Azure AD application
• Step 5: Assign Azure AD roles to the application
