You do need a current Excel version to make this project work. The difference here is that the bad guys can study the password generator embedded in any publicly available password manager, while they have no access to your home-built one. Note that this project necessarily relies on Excel's pseudo-random algorithm. It doesn't use macros or fancy stuff, just ordinary Excel functions, albeit some you may not have seen before.
But building this little project doesn't require advanced knowledge, just the ability to follow instructions. You’re not going to cobble up a handmade antivirus utility. You're not likely to construct your own globe-spanning network of VPN servers, for example. Some security tasks are undeniably beyond the do-it-yourself realm. We can help you build it, using Microsoft Excel. If you're paranoid enough, you might want to create your own random password generator. In theory, a hacker who knows the algorithm and has access to one of your generated passwords could replicate all subsequent generated passwords (though it would be difficult). In most cases, though, the program uses what's called a pseudo-random algorithm. The question is where do you get those random passwords? Just about every password manager comes with its own random password generator, some of which are better than others.

A hacker might guess a simple-minded password like Fido or crack it by brute force, but nobody could guess something like P5$e?KqA+unh$RhPTlp1, and brute-forcing it would take impossibly long. Once you have all your passwords safely stashed in the manager, replace any weak ones or dupes with unique passwords nobody could guess-and not even you could remember. Don’t try this without help-get a password manager. Do create a long, random, unique password for every website. Don’t use simple passwords like your birthday or your pet iguana’s name.
