It could be a two-word password, that much is true. But knowing what little he knows of Praxian society he somehow doubts that they'd leave their security to something that easily cracked. And besides, if they're only going to get one chance at this, it's better to have figured out all the possibilities beforehand. Especially given that it'll make it easier to pick out which option seems the most reasonable.

"Protection, maybe?" he offers, mostly as alternative to what she's suggested. It's not impossible that there's something related to heat in the password, but it's not the sort of thing he'd really choose, and never mind how important geothermal energy had been to the Praxians as a whole.

There's a pause there, and then he speaks up again.

"Actually, does Praxian even still have a term for sun? Or is it something that's become so archaic that it isn't in use anymore?"
