Managing personal Outlook.com account settings, security, and privacy
Hello, I’m Virginia a fellow Windows user.
I’m sorry to hear that you’re experiencing problems.
Alas there’s no option to circumvent 2fa so you’re only option is to see if the original password is saved under the browser’s password manager, if this is what you’re using & you have another device then go offline & check to see if the original password is still showing on the phone/other device.
If not then you’ll need to use one of the backup codes shown during 2fa set up which should’ve been manually saved/printed out.
