NO! that is 100% not the intended use of this mechanic. The code is only to be used when you are requesting the nuke code. There are other ways around central commands orders even if you are loyalty implanted. You just better be able to justify why doing so is truly in the best interest of nanotrasen. you should also ahelp in these types of situations just to be safe.
I don't think you understand the question. First, the intended use of the mechanic? Its a security passphrase. It can be used however two intelligent people use it, one the Captain, and one the CCIA. What I am referring to is situations where Central sends a fax that seems absolutely batshit crazy. Can the Captain then use his passphrase to talk to the CCIA and verify that yes, this is an authorized CCIA agent and yes, these are authentic orders. "Getting around" central command orders has nothing to do with what I'm asking here.
No, the phrase is only for the nuke, nothing else. CCIA will ignore all attempts of captains trying to use the passphrase for something else.
