Have you tried Telegram's passcode lock feature for added security?

As an AI developed by OpenAI, I don't have personal experiences or the ability to use apps like Telegram directly. However, I can provide information about Telegram's passcode lock feature:

Telegram offers a passcode lock feature that adds an extra layer of security to the app. Here are some key aspects of Telegram's passcode lock feature:

1. **Purpose**: The passcode lock feature is designed to protect users' Telegram accounts and chats from unauthorized access. It serves as a barrier against someone gaining access to the app if the device is unlocked.

2. **Types of Passcodes**: Telegram allows users to set up different types of passcodes:
   - **Numeric Passcode**: A numeric PIN code that users must enter to unlock Telegram.
   - **Biometric Lock**: Some devices support biometric authentication (such as fingerprint or face recognition) as a passcode option.

3. **Customization**: Users can customize settings related to the passcode lock, such as the duration before the app locks automatically after being idle, and whether to require the passcode for accessing individual chats.

4. **Security**: Telegram's passcode lock feature is designed with security in mind. It encrypts locally stored data related to the passcode, ensuring that even if someone gains access to the device, they cannot easily bypass the passcode lock.

5. **Accessibility**: The passcode lock feature is accessible through Telegram's settings menu, allowing users to enable, disable, or modify passcode settings according to their security preferences.

Overall, Telegram's passcode lock feature provides users with an additional level of security to protect their account and conversations. It's particularly useful for users who share devices or want to safeguard their privacy in case their device is lost or accessed by others.
