Conditional Access Applications

bfry2461 This is a normal behavior. The Microsoft Authentication Broker facilitates the SSO across a bunch of different services and apps. It handles token exchange so you don't have repeated authentication. Some devices have it built into the operating system while others like MacOS or iOS have the Microsoft Authenticator to use instead. 

A "success" status with conditional access as "not applied" is also normal because the broker has enabled SSO. Its always a good idea to review your conditional access policies and check for any exclusion or by-pass rules that you may have set. It's likely you've done something like this, but it doesn't hurt to review it on a regular basis.

Hope this helps.
