Unique Steamid Doors?

Let’s say I want only my steam id to be able open a door, so i stand on the spot needed to, i shoot press the button and it opens but only for my steamid. I remember there were ways to do this in gold src but i have long forgotten, and might not even be available on source.

you would have to either make a mod or write some Lua, restricting the restriction to gmod only.

That’s lame, I won’t be able to do it because this is for tf2

You could do it with sourcemod probably, or a modded mani script.

I don’t think its possible without a mod, would be cool though.
