Nice!

In what scenario would I use this system?

Yeah! This guide is useful:)
and to answer your question (even if i’m not the one who made the guide), it could be a game where you play levels to get a number, then in the password you unlock a thing to get something. Or it could be an escape room, and you need a password. Then you escape!

Just to make it more organized next time, use drop downs
Other than that, very good!
