Apple Device Email Setup

I have an old sbcglobal.net email address originally accessed on yahoo, which still works, but is now serviced by Att. I access my mail on a pc with outlook, and it is set up as an imap, and I never actually go to yahoo. I use apple mail for a phone and iPad. When I set up the account on the apple devices and had to pick an account type, I chose Other and it automatically got named an sbcglobal account type. Was this the correct way to set it up? There are a handful of choices, and outlook seemed wrong, but Yahoo was an option so should I have chosen that? I’m asking now because my email password is being rejected on all of my devices except the yahoo website. Some research suggests I have to remove my accounts and re-load them with OAuth to meet new Att security standards. If I am going to do that, I want to make sure I am doing it right and getting all devices to be synced for email, which has not been happening.

Thank you for any help you can provide.
