I was gonna ask about the biometrics part in a separate 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.
Gpg? I get nervous when people say that instead of a symmetric key system. When a quantum computer powerful enough gets invented, all non-quantum resistant asymmetric encryption systems will be broken. Honestly why not just use AES 256 just in case a quantum computer gets invented?
