This is the problem, if you can't even imagine this case. Someone in their 70s who isn't great with computers would likely be very happy to share their password with a tech-savvy child who can do some things for them. Passwords make this really easy, and you can even register a second MFA that goes to the child's phone/TOTP.
You don't even need to be in your 70s or not tech-savvy. Password-sharing happens frequently between spouses, children/parents, friends and probably a lot of other cases.
