Is there a way to restrict the acces to the bot savely?

[pinpox]

I want to be able to share inforamtion to certain users.
Is it safe enough to do something like:

Telegram::Bot::Client.run(token) do |bot|
  bot.listen do |message|

    case message.text
      if message.from.id == "My super secret id"
    when '/start'
      puts message.from.inspect
      bot.api.sendMessage(chat_id: message.chat.id, text: "Hello, #{message.from.first_name}")
    when '/stop'
      bot.api.sendMessage(chat_id: message.chat.id, text: "Bye, #{message.from.first_name}")
    end
    else
      bot.api.sendMessage(chat_id: message.chat.id, text: "Not authorized")
    end
  end
end

Any better/safer way?

I don't see any issues with your approach.
