To lock your messages, go to “Settings”, “Privacy and Security” and tap on “Passcode Lock”. You will be asked to set a four-digit passcode and confirm it.

Telegram: Which Secure Messaging App Is Better?
telegram russia samsung best encrypted private messenger apps for android Whether you no longer want to let redundant chats clutter the precious storage of your device or wish to shield your personal chats, the auto-delete timer is for you. When you set an auto-delete timer for a specific Telegram chat, all of its content including images, videos, and documents are automatically deleted after the timer expires. If you don’t want messages in your secret chats to hang around forever, Telegram lets you set self-destruct timers to permanently remove them. After a message is received, it remains in the chat for a predetermined period — you can choose times between one second and one week – before disappearing. This means you can start typing a message on your mobile and continue on your desktop. The draft will remain in the editing area on all sync devices until it is sent or deleted.
Bot API: lets you build programs that use Telegram messages for an interface. You don’t need to have knowledge of MTProto encryption protocol. The intermediary server will handle all communication and encryption with Telegram API for you. However, Telegram only uses this encryption in calls and in its “secret chats” feature, not in regular chats. Those are only encrypted client to server. Meanwhile, WhatsApp, the supposedly less secure service, has used end-to-end encryption in all messages, calls, and video calls since 2016. Telegram Chat Options You can surely delete messages that you have sent, but did you know that Telegram has brought a new feature that lets you delete messages sent by other users too. That’s kind of weird, but this feature is for users who prioritize privacy over everything. To use this feature, just select the received message and tap on the “delete” button. Now, select “Also delete for X” and tap on “Delete”. The message will disappear from both ends without leaving any trace.
