Telegram User Protecting Their Chats Using Passcode and Face ID Lock
Khamosh Pathak

Telegram is great for messaging individuals and large groups. You can add an extra layer of security to Telegram using a passcode, fingerprint, or Face ID. Here’s how to protect Telegram messages with a passcode on iPhone and Android.

Telegram has an app-based passcode lock system. This passcode lock needs to be set up on each device individually. The passcode isn’t synced between your devices, and it isn’t linked to your Telegram account. If you forget the passcode, you’ll need to delete and reinstall the Telegram app.

You’ll get all your Telegram chats back if this happens, but you will lose out on all the Secret Chats. The messages are deleted, as they aren’t synced using Telegram’s servers and are instead stored locally on the device.
