Show the issue, but block personal info. I'm also a 20yrs+ customer and have not see that before. Are you running any security software besides MS Defender? Windows home or pro? Have you tried with Firefox in Troubleshoot Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

Let me login...

Can not access account without being authorized by Sorcure and providing them more personal information Other browsers do not requireReason?.

I was able to get in after 2FA with no issues. see screensho This sounds like a phone call is needed for that personal info request.

Use malwarebytes, home version. Several long phone calls made before posting. They seem to know of a problem because a ticket had already been created.

Great. Mark this as resolved since it's not a browser issue and have a a good day.

Thanks
