I have the worst PW system ever. But it works in my eyes.
A) a "throwaway" PW for most sites. Sites I care little about. I get hacked, and no big loss.
B) a "good" PW (no words, no repeating characters, incls special characters, etc (and generated via Keepassxc)) that I use with "important" accts, but I also use a Yubikey 5C (and 5C nano) with those *important* accts, so I'm probably safe there
I cannot stand PW managers. They have failed me many times over (didn't save the new PW properly, won't auto-fill when I need it to, etc). I lost my old/main ProtonMail acct to a bad PW entry into LastPass years ago, not going back.
So, this is bad/unwise advice. And the handwritten, local (encrypted, even) .txt file I don't use, either, because that adds inconvenience, and life is too short to care about my garble from being stolen on the Web.
Again, *real* accts I have get better treatment, most accts I have are not "important"
Hope you're good!
