Opening door with a word?

I want to make a game that is the same idea as "Guess That Character" or something like that but I can't figure out how to do it. Can someone help me, please?

Something like this should work if you put it in a part and name that part after the character the player has to guess.

game.Players.PlayerAdded:Connect(function(plr)
	plr.Chatted:Connect(function(msg)
		if msg == script.Parent.Name then
			script.Parent.CanCollide = false
			wait(1)
			script.Parent.CanCollide = true
		end
	end)
end)

You can also use collision filtering to make it so that only the player who said the name can pass through for the time its open.
