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.
He does recommend using the built-in browser's password managers; he just had beefs with how the extensions, which the non-browser password managers have to contend with, are implemented, and with the security of the vendor's network and software. He himself uses Chrome password manager.
Exactly but that's why I will not use a password manager at all. Better safe than sorry ๐
