When I type in address fields, emails that aren't mine show up in Edge's autofill suggestions. Doing a quick search of the ones I can tell are names turn out as people in my university.I remember logging into the edge browser of a school computer in 2023, and accidentally linking my Microsoft account to the PC.

Edge Autofill woes

Windows Version 21H2 Edge Version 98.0.1108.56 Greetings folks, Over the years I've always manually typed in my email address in sign in forms and of late it's become a bit cumbersome. I've always avoided using the Edge auto fill in method as I was under the false impression that to use this method I would also have to enter my password for autofill, which I don't want to do, I prefer keeping passwords in my head. After learning that I can have Edge just autofill my email address without the password, I've been using it to great effect. The problem is, Edge seems to be automatically remembering 2FA text and app generated authentication codes and suggesting them in a drop down list whenever they have to be input. While I'm aware these codes are time-sensitive and pose no security risk it looks a bit messy having a whole list of them pop up whenever a 2FA field presents itself. I'm aware there is a delete entry button next to each entry but clearing them all each time would be more annoying than having to manually enter my email address. Is there anyway to turn these automatically saved autofill entries off? All I want is my email address saved. I've included a screenshot to show what I am on about.

I have done that to the "edge" browsers. But I still do not get the 'autofill'. Any other suggestions?
