Share Your Live Location Premium app icons 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.
Next up, tap Sound and then choose your custom notification sound located under the Telegram Tones section. Make sure to tap Done at the top right to finish. Interestingly, Telegram names your custom notification sound as Cloud Tone and also allows you to upload any audio as a notification sound for a chat.

Tap your profile picture here to see everything you've uploaded in the past. You can scroll across them; tap the Set as Main Photo option that appears on the top-right menu (as three dots on Android or Edit on iPhone) to set an older image as your current profile picture. You can use this to, for example, keep your personal and professional lives separate on Telegram without having to use another messenger app. Additionally, subscribers can enable a setting in Privacy and Security to automatically archive and mute new chats, helping organize even the busiest chat lists. Telegram Premium includes new tools to organize your chat list – like changing your default chat folder so the app always opens on a custom folder or, say, Unread instead of All Chats.
