[Spoilers] Does anyone have a hint for the computer inside blackbridge grotto?

I already have the admin key

but am looking for the super admin key with archive access. Can anyone give me a hint as to where to find this? In the log I see it's said that it doesn't conform to the normal format, so I assume I can't just keep trying every name I find.
