startup recovery firmware nvram firmware-password

                          While trying to get into recovery mode, I used this:

sudo nvram recovery-boot-mode=unused

... hoping it'd take me directly to recovery mode. Instead, it prompts me for the firmware password. Which I don't know. And I can't clear NVRAM without the firmware password. So, I'm stuck in a reboot loop.

Yes, I'm an idiot. How do I get myself out of this mess?
