Want to lock apps without downloading extra software? Learn how to use built-in tools on Samsung, Xiaomi, OnePlus, and other Android phones to secure your apps with passwords or biometrics – no third-party apps required.
Your smartphone contains plenty of personal information, including images, bank accounts, social network profiles, and private messages. Locking specific apps provides an additional layer of security, particularly when sharing your device or preventing unintentional snooping.

MIUI has a built-in App Lock feature that is super easy to set up.
This works for apps like WhatsApp, Facebook, Instagram, Gmail, and more.
