Semi-relatedly, I had my parents sign up for https://www.charlie.com/ There are a bunch of great anti-fraud features including one that lets me be a co-pilot on their account.

Some features: it doesn't allow transactions while they are asleep, can block all transactions online except for merchants that you allow, limit international spend, and they have a feature that you can forward any email that you are curious about and it'll tell you if it's likely to be fraud.

highly recommend.
