The god of secrets should be an unknown entity that players aren't even sure exists, to say nothing of the player characters.
You're being overly literal, I think, and not tricky enough. Some secrets are best kept in plain sight, after all; hidden within red herrings and false leads. Perhaps the most effective god of secrets would have a name known by everyone.
A name, not a true name.
Vecna, though, is effective as he is. The details of his mortal and undead existence are shrouded in rumors and lies, much of it carefully suppressed by two ruthless Keoish organizations or by his cult. He's the
Whispered One - his name (
a name) is hinted at to tantalize those seeking for deeper knowledge, but it isn't well-known enough for him to be a bogeyman - he's too esoteric to be used to frighten children. He
wants to be a little known - the whispers come from his own dessicated lips. He needs to attract those whose secrets he intends to steal; he needs a lure. A name is useful for this. A name is a promise, and it's also a disguise.
I like Vecna the god, a sinister being with knowledge of things even the gods of magic are ignorant of. Vecna the lich bores me - D&D is full of liches, and we don't need nearly so many.
As for fooling the
players, I loved Nfft's comment - there's no need for the
players to know his status, or even if he exists or ever existed in your campaign.
