I have a 2020 iPhoneSE, a 2017 iPad Pro, a 2017 iMac Retina with macOS 10.14.6 “Mojave” and a 2010 Mac Pro with OSX 10.6 8 “Snow Leopard” which I use for most of my serious work. (Yes, I prefer using “Snow Leopard” over all the newer macOS versions.)
I have very few apps on any of the i-devices. I use them primarily for TEXT messaging and occasional access to the internet. I have updated the iPhone and iPad to iOS 14.2.
It seems to me that two-factor authentication will turn out to be far more bother than it could be worth.
If I turn it on, then after 2 weeks I will not be able to ever turn it off.
The iMac with Mojave continually pesters me to set up two-factor authentication.
(By the way, I do not want to “upgrade” the iMac to Catalina or Big Sur because it works just fine with Mojave for the things I use it for.)
Can I continue to live without two-factor authentication, and can I turn off the pestering?
