MFA fatigue wouldn't be such a big problem if their MFA and SSO implementation was not so utter shit.

Whenever I get a signin prompt, there is literally no way to tell what I'm signing in for.

When the MS Authenticator app receives a MFA request notification, there is, yet again, no way to tell what service the request is for.

To add insult to injury, when I need to signin again for a SharePoint guest account, it consistently fails to correctly redirect me back to the SharePoint folder.

Microsoft's MFA is just security theatre. Take MS Teams for instance. Why does it ask me to sign in again, and yet still allow me to read messages that are already on the screen? Worse yet, the MS Teams desktop app can still receive new message notifications and display them while I have not re-logged in yet.
