    I was curious about that, so I looked into it; KeePassXC is having some mixed messages about it:

    https://github.com/keepassxreboot/keepassxc/issues/1870 says "awesome!"

    https://github.com/keepassxreboot/keepassxc/issues/1996 says "go away"

    and I can't figure out what is going on with https://github.com/keepassxreboot/keepassxc/issues/3560

    They reference https://github.com/kryptco/kr-u2f in one of the issues, but it was bought by Akamai and the code was never under an open source license to begin with :-(

    Don’t use the same password on multiple sites. I have my own password generating shell script which uses strong cryptography which takes a secret and a site name, and generates a strong password (secret is protected with key stretching). Other similar solutions exist (LastPass, etc.)

    I do not use a browser-based password generator, because of the Javascript insecurity issues. I use a shell script, with a small C program to handle the core cryptography, to generate secure passwords.

    I run the password generator in a terminal window, then copy and paste the password in to the site I am trying to log in to.

    It’s a fairly complicated shell script, since it also has to deal with nonsense like stupid arbitrary password rules (e.g. Southwest considers an underscore to be a letter, and insists at least one non-letter non-number punctuation is in a password; some places require a password to be 8 characters or shorter; etc.) and also provides login information so I can also remember my username.

    As recently as 5 or 6 years ago, there were issues with websites which wouldn’t let you copy and paste a password in to their password field; Firefox has always had a “ignore any Javascript which stops pasting” special rule in about:config I had to use. I haven’t seen one of those in a while; developers finally got a clue and realized that password managers exist.

    One weakness this setup has is that anyone with the “master key” can get all of the password generated by the password generator. My workaround is to use a separate master key in a virtual machine for critical passwords, such as online banking ones.

    Shameless plug time:
