1Password allows you to share login credentials and stores/generates TOTP which can be used across multiple users/machines. A Yubikey as 2FA is another good option but that is not widely supported yet. Add another phone line for a phone that stays home and is the 2FA phone (or a Google Voice to a shared email account, with all family members phones as the Gmail 2FA, since it supports multiple phones) #1 rule, pay for domains out the full 10 years, every year, everything else is gravy. As long as your estate owns the domain, things can be fixed even if some mail is lost. They have a decade to sort it out ;)
