Im lookin for the first password needed in pandora tmrw.

Usually you will find the keycodes either on computers you access or by interrogating guards. It's usually best to do that rather than just getting them here as that keeps you in the flow of the game. That being said, I'll give you the first one encountered in the game and let you find the rest on your own...
