For the last 10 years or so I used a password hashing mechanism instead of a password manager to generate a different password for each site based on the URI and a hash word.
Over time I use one of the compatible plugins in Firefox or Chromium derived from the original password hasher. Today I am using Quantum Hasher in Firefox and PawHash in Chromium.
I am considering moving to Brave as my main browser but I need a password hasher before I can make the jump. I hope that this extension is attractive enough to justify its integration.
