## Basic setup for Mobile App

### Select wallet mode

{% hint style="warning" %}
This guide is based on **D’CENT mobile app version 8.0.0**.
{% endhint %}

If you are launching the mobile app for the first time, you will need to go through the initial setup and select a wallet mode. When the app launches, select **“Biometric Wallet”** as shown below.

<div align="left"><figure><img src="https://3989759490-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M50hxCNYm5Y8rdrUs_k-887967055%2Fuploads%2FVWWWXMWZgpC1RlHUOfCU%2FiOS-1.png?alt=media&#x26;token=faf0ebdc-ff1a-450a-8251-9209dfe6fc97" alt="" width="377"><figcaption></figcaption></figure></div>

You can change the **wallet mode** at any time from the **Settings** tab in the mobile app. If you are using a **biometric cold wallet**, make sure to set the wallet mode to **"Biometric"** in the mobile app. For instructions on how to change the wallet mode, [**refer to this guide**](https://userguide.dcentwallet.com/mobile-app/mobile-app-setting-menu/mobile-app-dcent-walletmode).

### Register password for Mobile App

Register mobile app password for access protection. To set the password, **enter the same 6-digit number twice.** Mobile App password is required every time you run the D'CENT mobile app. Make sure to remember it.

<div align="left"><figure><img src="https://3989759490-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M50hxCNYm5Y8rdrUs_k-887967055%2Fuploads%2FLZw1neOH58VR2SD2iiwW%2FiOS-2.png?alt=media&#x26;token=7d51b107-bd10-4a5a-a250-e08dbb9ea22c" alt=""><figcaption></figcaption></figure></div>

{% hint style="info" %}
Mobile App password can be changed from the [**App "Setting" menu**](https://userguide.dcentwallet.com/dcent-app/mobile-app-setting-menu) at any time. Instead of password, you can also use biometric authentication to protect access to your wallet if your mobile phone supports the feature.
{% endhint %}

### **Mobile App Permission Settings** <a href="#mobile-app-permission-settings" id="mobile-app-permission-settings"></a>

A permission request popup will appear when you launch the D’CENT mobile app. Review the permissions being requested, then click **“Confirm”** button to proceed.

<div align="left"><figure><img src="https://3989759490-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M50hxCNYm5Y8rdrUs_k-887967055%2Fuploads%2Fm5JLhSeCCWTiyKtyg5pb%2FiOS-3.png?alt=media&#x26;token=0d3edd41-9427-48d4-84e6-d58c3de7a9d2" alt="" width="377"><figcaption></figcaption></figure></div>

Next, click the **“Allow”** button for both the **Notification** and **Find Bluetooth Devices** permissions to continue.

{% hint style="danger" %}
The **Notification** permission is optional. You can click the **“Don’t allow” button** and still connect your wallet without any issues. However, the **Find Bluetooth Devices** permission is **required** for syncing with the cold wallet. If access is denied, the cold wallet cannot be synced, and usage will be restricted. **Therefore, be sure to allow this permission.**
