iPhone 8/Plus Isn't 2 factor authentication mandatory?

[AMSOS]

I moved from Snow Leopard - Yosemite - Sierra and now Mojave.

I was given to understand that at one point 2 factor authentication is mandatory. So, how come I am still able to get by without using this?

I use a Mac laptop and iPhone.

Is there some way to sync iMessages from my old phone to new one without switching on 2 factor authentication?

Thanks!

Apple can't force you to turn it on.

But they can prevent you from turning it off once you have it turned on. And that's where the mandatory part comes in.

Eyoungren is correct. Once you turn it on for the first time, you have (I believe) two weeks. If 2FA is not turned off during that time, it then becomes mandatory on the account.
