ive already made a button door but it just sets the cancollide property false for 3 seconds, other players can also go through the door heres my code,

button = workspace.button
button.Touched:Connect(function(hit)
	local hum = workspace.button.Touched:Connect("FindFirstChild")
	if hum then
	game.workspace.buttonpush.Transparency = 0.75	
	game.Workspace.buttonpush.CanCollide = false
	wait(3)
	game.Workspace.buttonpush.CanCollide = true
		game.workspace.buttonpush.Transparency = 0

	end
end)

Your best option is to use a LocalScript instead since you want only specific players to go through it.
However, if you really need to have it Server-Sided for whatever reason, you can also rely on the Touched event.
I scripted this some time ago, but I’m sure you can figure out something useful from it.

local part = script.Parent -- the part that changes its CanCollide behavior
local Group = 0 -- 
local minimumRankLevel = 0 -- you can modify these settings if you want to make it User-Specific
local db = false
local db_2 = false
local function onPartTouched(otherPart)
	local partParent = otherPart.Parent
	local humanoid = partParent:FindFirstChildWhichIsA("Humanoid")
	repeat wait() until humanoid
	local character = humanoid.Parent
	local plr = game.Players:GetPlayerFromCharacter(character)
	if humanoid then
		if plr:IsInGroup(Group) and plr:GetRankInGroup(Group) >= minimumRankLevel then
			if db_2 == false then
			db_2 = true
			print(plr.Name.." is in the group and their rank is "..plr:GetRoleInGroup(Group)..".")
			wait(0.5)
			part.CanCollide = false
			wait(2)
			part.CanCollide = true
            db_2 = false
			

			end
		end
	elseif db == false then
		db = true
		print(plr.Name.." is not allowed to go through this area! ("..plr:GetRoleInGroup(Group)..")")
		plr:LoadCharacter()
		wait(1)
		db = false
	end
end

part.Touched:Connect(onPartTouched)

It’s not perfect, but what it basically does is check if the player is in the group and their rank, if it matches with the variables then it will let them in. If not, it will respawn them.
Good luck!
