    Wait, what ? Two-factor authentication codes on a TI-89 ? ? ?

    Code:
    key_parm = base32_decode(key, x, 16);
    https://github.com/arcanericky/ga-cmd/blob/master/src/codegen.c#L15

    Really? There are 32 characters in a totp secret, yet you only decode 16? wtf?

    Well, thankfully, I figured out the problem !

    Now I can use two-factor on my calculator :-)

    I just need to put the totp secret in a variable instead of hardcoded into my program, get my program to read from that variable, and then release the source code (which really is ga-cmd but fixed variable widths, romcalls and shit)

    Thanks a ton! Finally we won't be hearing complaints about Steam transactions needing a phone!
