tl;dr “If you want to use an online password manager, I would recommend using the one already built into your browser. They provide the same functionality, and can sidestep these fundamental problems with extensions.”
I can only speak for myself but his article confirmed my suspicion about any Password Manager, even Bitwarden and I never have or will use any online Password Managers. I create all my Passwords individually with my own algorithm in my head and can always recreate them.
Password managers are technically a convenience at the cost of security. At least compared to memorizing dozens of long unique passwords. I’d probably host my own if I were going to use one. For now I just memorize a ton of random characters and then reset my password when I fail to remember. 😅
