> - built-in password managers only work for websites - I store many non-website security credentials in my password manager

The one integrated with Firefox supports integration with an Android stored password entry tool. As a manager it's of very poor quality - better to do all your actual management from desktop Firefox - but as a tool to enter a stored password into an app, or to save the password you just entered, it works quite nicely.

Firefox does have that service

2, 3, 4 are handled by Chrome, for example. These really are trivial features that any decent corpo can get right.

1 obviously isn't.

Oh, yes, I forgot a pretty important one, I don't want to upload all my passwords to google. Offline storage, and direct device-to-device syncing.

Last I checked I couldn’t export Chrome passwords (aka offline backup), couldn’t add non site passwords, and couldn’t manage non site based passwords/secrets with chrome password manager. And that was a month ago?

You can import chrome passwords from other browsers so I think you can also export them for backup.

I agree that I don't think you can add custom secrets.

Sure enough, looks like I was wrong re: export. Thanks! Unfortunately other things are still an issue - https://support.google.com/chrome/answer/95606
