# How to Unlock the Device Screen using the Oloid DeviceLock App with Face Credential

> This document provides step-by-step instruction to unlock the Device Screen using the Oloid DeviceLock App with Face credential.

## Introduction

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

## Prerequisite

* The device must have a functional front-facing camera.

## Steps to Unlock the Device

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

   > [!NOTE]
   >
   > **Note:** The Device Lock app is displayed automatically, as it always runs in Kiosk Mode.

   The Welcome screen is displayed.
2. Tap **Login with Face**.

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