Too Long; Didn't Read
You don’t have to trust Google, Microsoft, or the pope to have your passwords “auto-filled” The ultimate solution will be to have a separate, randomly generated password for every login. For me, I struggle to remember my birthday already, so I have to use a password manager. I use a local password manager on my computer: I just stick with a password, which is the only password I memorize. I save the encrypted passwords file on a cloud storage drive (ex: google drive or Dropbox): And decrypt the file on any terminal device. This way, google has a meaningless encrypted file, and I have a cross plateform system that works perfectly.
