You can actually make the pin longer if you change this line: https://github.com/AuroraWright/Luma3DS/blob/master/source/pin.h#L33 and compile it yourself.so they added a password which is the good news. Bad news is there's only like 20 combinations. I forgot my password so i just guessed and eventually i got it. L and R need to be implemented or start and select or else this doesn't work. That and anybody who has and understanding of arm9loaderhax could simply delete the luma files and add new ones to bypass the passcode, though i'm not worried about that considering nobody knows how this stuff works. This is a step in the right direction though.
