The 2 digit code is legit. It's similar to the way MS MFA authentication works. I even tried to remove my Google Authentication app and that didn't help (I checked settings in there, too).
Thanks for your suggestions.
I have reviewed the security settings on my account and I clearly have 2FA or MFA turned off. I don't have any other security setting(s) that are obvious to me. I have a crazy long password so I have attempted to remove certain security settings off but that has not helped. This is really puzzling.
I already have family Dish access so it's not urgent. I do have a secondary Google account already so I might just try what you're suggesting. In fact, that sounds like the easiest solution. I'll ask my SIL to switch accounts the next time we chat.
