Scary notification: Microsoft was used to sign into ...

This pop-up appeared underneath my 1Password extension icon in Firefox.

Pretty terrifying -- I surely never want to have 1Password sign me into anything without me explicitly requesting and approving it.

Best I can tell, the pop-up didn't correspond to any action taken by me. I have multiple browser windows open, and I'm not sure if I saw this when it first appeared or if I "revealed" it when switching to another browser window.

I am not signed into Microsoft/Office/Outlook, and I do not believe I went through an explicit sign-in process for any other site today.

I see other some other users have reported this symptom, but the cause/resolution isn't clear to me.

Not sure how to repro but am happy to provide any information or follow any suggestions to help diagnose it.
