How to Lock Apps with Your Fingerprint on Xiaomi Phones in 2026 (HyperOS Guide)
Privacy has become more important than ever in 2026. Most smartphone users store personal photos, banking information, social media accounts, and private conversations on their devices. While locking your phone with a fingerprint is a good first step, it may not be enough if someone gains access to your unlocked device.
Fortunately, Xiaomi smartphones include a built-in App Lock feature that allows you to protect individual apps with your fingerprint. This means that even if someone unlocks your phone, they still won't be able to open selected apps without your authorization.
In this guide, you'll learn how to enable App Lock using your fingerprint on Xiaomi phones running HyperOS.

When enabled, protected apps require:
