Something that's read out over the radio?

Could be: but if it were it would probably be a one-time use code for
that particular flight.

No problem.

My recollection of this is that it wasn't a single-use code but a code that
was valid for some window (ie. a day or an hour). Of course, my
recollection could be completely wrong (even to the idea that there's a
password at all {8^), but this sounds a lot more TSA-ish than a single-use
code.

Remember: these are the same people that don't even sync up with ATC when
tracking an aircraft with a failed mode C, but that just scare everyone
into the streets.
