I was gonna ask about the phone biometrics part in a sepatate question, but its both about security, so might as well combine it in one post.
Okay so I don’t use password managers. I just try to make easy to remember passwords 3-4 random words + 3-4 random numbers. Online accounts can’t be brute forced anyways. For offline accounts, I just increase the words and numbers. For mobile I don’t use biometrics, although I’ve been testing whether or not I want a pin + no biometrics or alphanumeric password + biometrics. I just can’t decide.
Bitwarden for my personal stuff, KeePass for work (like to keep everything separated). Biometrics on devices that support it. I used to do what you did, and then Facebook got hacked and all my other online accounts fell like a house of cards, found out when my friend texted me asking WTF was going on and why was I posting links to porn sites everywhere. So, password manager and strong passwords for all the things. MFA is something that needs to become more common as well.
