This feels like a weaker version of GRC's Off The Grid system. https://www.grc.com/offthegrid.htm
It doesn't require you to remember something different per website. It's designed so that you can turn any site name (E.g. Amazon) into a secure password which is unique to you. If you really need a completely offline solution, I don't think it gets too much better than that.
All of these systems are great until you run into "password must be 9-11 characters and contain two symbols from a hidden list of acceptable symbols, which we will not expose to the user but instead only inform you you've chosen the wrong symbol". I can't see myself relying on a system like this for more than providing a secure password to my digital password manager.
That is quite a nice read. I think I'll try using this system, as it looks fun. Thanks for that idea.
I've never really had a use case for it myself. I'm happy using Bitwarden at present. It's certainly a fun read and a good solution for anyone in need of a completely offline solution.
I really like how easy it is to customise it so that even if someone got a copy of your square, they wouldn't necessarily be able to get your passwords. Changing your starting row or column or adding a few characters at the start of the domain will completely change the output. I'd imagine you'd need both the square and multiple passwords to even attempt to brute force a solution back out of it.
