Locking apps on Android can be a crucial step for enhancing privacy and security. While there are many third-party applications available for this purpose, some users prefer not to download additional apps due to storage constraints or privacy concerns. This guide explores how to lock apps on Android without using an app, focusing on built-in features and methods that can be employed.

Using Android's Built-in Features

Screen Pinning

Screen Pinning is a feature available on Android devices running Lollipop (5.0) and above. It allows you to lock your device to a single app, making it impossible to switch to another app without entering your device's PIN, pattern, or password.

1. Enable Screen Pinning:

- Go to Settings > Security (or Security & location).

- Scroll down and find Screen pinning.

- Toggle the switch to enable it.

2. Use Screen Pinning:

- Open the app you want to pin.

- Tap the Overview button (the square button) to open the list of recently used apps.

- Swipe up on the app and look for a pin icon at the bottom right corner.

- Tap the pin icon to pin the app.

3. Unpin the App:

- To unpin the app, press and hold the Back and Overview buttons simultaneously.

- You will be prompted to enter your device's security credentials to unpin the app.

Guest Mode is another feature available on most Android devices. It creates a separate user profile with limited access to your data and apps.
