Do you use `pass` as password manager on your machine?
There is an extension to verify your passwords against the HIBP database of known passwords and make sure that your password wasn't exposed during a data breach. (Of course without telling your password apart)
This extension is packaged on #Fedora as pass-pwned.
Brian "bex" Exelbierd wrote an article about it, and how to install it on any other distro on opensource.com:
I'm using pass only with this command for my new passwords :
$ pwgen -sy 64 -N 1
Don't think I need that extension since i'm pretty confident that they're safe to use 😅
