I'd love to work out the entropy of something like thisanfd work out how secure it is. I suppose if it's generating a melody instead of just random notes then that lowers the entropy so it would have to be higher. I just really love the idea of unlocking my computer with a midi keyboard. You could definitely do this with PAM authentication in Linux and probably MacOS too. Or if you found a way to encode text using music notes then you could create a password manager that takes your existing passwords and converts them accordingly to after you press the midi keys. So many ideas 😆
