Whitelist System does not detect whitelisted names. How to fix?

Basically, I am trying to create a whitelist system for which when the script detects that there is a whitelisted user the user is able to use the speed agility,

if game.Players.LocalPlayer.Name == {"MyBestFriend","mony111133333"}
then
    game:GetService("UserInputService").InputBegan:connect(function(inputObject,gameProcessedEvent)
        if inputObject.KeyCode == Enum.KeyCode.W then
            game.Players.LocalPlayer.Character.Humanoid.WalkSpeed = 60
        end 
    end)    

else
game.Players.LocalPlayer:Kick ("You are NOT whitelisted, Join the Discod Server. Sorry!")
end

The reason for your code not working was because you are comparing the name (a string) to a table, and since the name is never going to be a table your condition was never met. Adding on to MakeYourEscape's answer:

local whitelist = {
    MyBestFriend = true,
    mony111133333 = true
}

game:GetService("Players").PlayerAdded:Connect(function(client)
    client.CharacterAdded:Connect(function(character)
        if whitelist[client.Name] then
            character:WaitForChild("Humanoid").WalkSpeed = 60
        end
    end)
end)

But instead of looping through an array I use a dictionary. I can then check if their name is in the dictionary. I encourage you use the UserId, since you can change your username, but not your UserId. And I don't use UserInputService since you don't need it in this case.

Well, first, you can only kick users through a server sided script.

I will explain the rest in the code.

--this should be a server script in ServerScriptService

local whitelist = {"MyBestFriend","mony111133333"} --Who is allowed inside.


game.Players.PlayerAdded:Connect(function(plr) --plr being the player, this runs when the player joins the game
	for _,v in pairs(whitelist) do -- this will go through all the items in the whitelist table
		if plr.Name == v then --If the player is found on the whitelist
			workspace:WaitForChild(plr.Name):WaitForChild("Humanoid").WalkSpeed = 60 --sets the player's walk speed to 60
			return "Allowed" -- End everything and let
		else
			wait() --go on to the next item in the list
		end
	end
	plr:Kick("You aren't on the whitelist") -- If the player wasn't found, then the function wouldn't be returned and ended, meaning They aren' on the whitelist!
end)
