## Introduction

The **Oloid DeviceLock app** enables users to securely unlock their Android devices using **QR credential**. After successful authentication, the device unlocks and redirects to the device **home screen**.

## Steps to Unlock the Device

1. Press the **Power** button or tap the screen on your device.

   > **Note:** You will only see the authentication methods (Face, Badge, PIN, QR Code and NFC/ID) enabled for you. Button names may vary based on configuration. Contact [Support](mailto:Support@oloid.ai) if no authentication method appears.
