As a computer expert himself, Vigilwould NEVER have made that devil's bargan. If I had data I wanted ANYONE to have, it would be burned onto a CD and handed over that way. NO ONE accesses Vigil's computer but Vigil!
As far as the team base goes, well, Vigil didn't trust the people running the team either. So before getting undressed to take a shower, he always ran the hot water long enough to steam up all the mirrors completely... as well as any hidden camera lenses. Other than that, he was never seen outside of costume when circumstances forced him to live at the base.
(Yes, Vigil was more than a bit paranoid. But when you're a villian secretly trying to reform - and even the team doesn't know - paranoia is a way of life.
