Telegram offers a few other handy options in chats. You can delete any message by long-pressing it, then hitting the Trash icon that appears. The app lets you delete messages at any time—even messages that the other person sent in a chat. Perhaps the most important and the best feature of the Telegram app is its security. It is based on the MTProto protocol that is built upon time-tested algorithms. It enables high-speed, reliable message delivery on weak connections. To lock a chat go to Settings->Privacy and Security->Passcode Lock and enable it. Once you create a passcode and enable it, you will be able to lock and unlock your chats by tapping on the lock icon at the top right of the app.
