      Yup. I suspect the message here is to discourage some consumers from using football team names etc. as passwords rather than cooling on password managers. There again maybe bugs discovered by the likes of @taviso have shifted the calculus?

      I can’t think of any bug that would cause a reasonable person to discard their password manager and revert to reusing weak, memorisesd secrets

      Those are not the only options, you could switch to a safe password manager or use a notebook. Security doesn't begin and end with passwords, It is not "reasonable" to continue using software you know to be dangerously broken!

      Dangerously broken? Do tell, we talking autofill or lack of encryption for "locked" modes?

      I don't know what Troy is thinking of, the kind of exploits I've seen in password managers are remote code execution vulnerabilities, allowing any website to take over your computer. For example, https://bugs.chromium.org/p/project-zero/issues/detail?id=1225 … or https://bugs.chromium.org/p/project-zero/issues/detail?id=693 …

          So maybe we are talking more specifically about password manager browser extensions? This distinction is very clear in 1Password, less so with the others where they are all plugin oriented. The second area of concern mentioned earlier is similar, malware reading the decrypted db

          There was no browser extension involved in the second link above. As far as I know, 1Password is similarly designed, relying on websockets for security. If you're concerned about malware, you should use application whitelisting - no password manager design will save you.
