Help Me: Firing Events With A Value?

I want to protect my game from exploiters that fire events to create parts. I don't want replies saying "this won't help at all!1", because I have a system that'd work with this.

Here's my local script context:

script.Parent.Activated:Connect(function()
game:GetService("ReplicatedStorage").PartCreate:FireServer("d85jh34hdfj3dg")
end)

Here's my server side script context:

game:GetService("ReplicatedStorage").PartCreate.OnServerEvent:Connect(function(Player)
local Part = Instance.new("Part")
Part.Parent = game:GetService("Workspace").Parts
Part.Name = "ClientPart";
Part.Position = Player.Character.Torso.Position
Part.Size = Vector3.new(4, 1, 2)
Part.BrickColor = BrickColor.Random()
Part.CanCollide = true
Part.Anchored = false
end)

Now how can I have the script only fire if the password is correct?

You need to add the password argument to the function you are creating on the server, so that you can check to see if it is valid.

game:GetService("ReplicatedStorage").PartCreate.OnServerEvent:Connect(function(Player, password)
	-- Check if password is correct
	if password == "d85jh34hdfj3dg" then
		local Part = Instance.new("Part")
		Part.Parent = game:GetService("Workspace").Parts
		Part.Name = "ClientPart";
		Part.Position = Player.Character.Torso.Position
		Part.Size = Vector3.new(4, 1, 2)
		Part.BrickColor = BrickColor.Random()
		Part.CanCollide = true
		Part.Anchored = false
	end
end)
