Authentication method policies should not reference non-existent groups.
Why This Matters
Authentication method policies that reference deleted or non-existent groups create a security gap. These orphaned references can prevent proper policy enforcement, leaving your tenant vulnerable to misconfigured authentication controls that may allow weak or unintended authentication methods.
What Aether365 Checks
This check verifies that all authentication method policies in your Microsoft 365 tenant reference only valid, existing groups. It appears in the Aether365 dashboard under microsoft-365 checks and alerts you to any group references that no longer exist.
