Hopefully this will stop the replies to comments complaining about stupid password rules: "Just use a password manager". Why would you ever trust someone else with something like this?
The advice should read "Just use a popular password manager that doesn't have a well-document history of being terrible, from a company that releases their regular security audit reports". The most basic form of "Do your own research" should reveal a long list of security incidents: https://en.wikipedia.org/wiki/LastPass#Security_incidents
