Seriously, all the people of my parents generation have a physical book with account names and passwords in it. You keep it in a safe place, and nobody can hack it remotely.
Plus, should your heirs or caretakers need to access it, it's all there in plain text for them.
Other than a few web forums, I don't use my phone for anything that requires a password. Certainly not for email, banking, or anything that involves personal data, money, or business. A lot of stuff, I don't do on my desktop either.
Anything connected to the internet is insecure. No, it's not as convenient to do things by phone or paper mail, but I value security more than convenience.
