Congratulations for making it that far! :-)
You need three items.
Find something "you" are in the Commander's suite on their computer.
Have a closer look at the crew dormitory. Use something you know (or someone else knows but did not remember).
And something you own. That will require a detour via the receptionist robot by talking them into handing out an item.
There's also a walkthrough on the internet - if you can find it ;-)
