Just for the record, I'm trying to help
you. I ditched OS9 the first chance I got and I have more bad memories of it than I do good. But I'm a graphic designer which means I pushed the system much more than the typical user.
I'm not trying to be mean or anything, I just don't care for OS9.
As far as the internet goes, I can remember telling my wife some time in 1998 that I would never use a credit card over the internet to buy something. That was because interception of CC numbers during shopping cart transactions was rampant, even back then. People were getting ripped off. That was pre-OS9 days. So, I remember the internet a little bit different.
Anyway, if I am helping, I'm glad to be of assistance. However, I do not know how you'd go about forcing 2FA to shut off entirely. Supposedly the link I provided does that. But, you know…Google.
