## Delete Device

**Starting from version 8.1.0 of the D'CENT mobile app**, a **"Delete Device"** option is available for removing registered biometric cold wallets. This feature allows you to delete unused cold wallets directly within the mobile app for better wallet management.

Deleting the device from the app **does not delete any of the private keys associated to the wallet accounts** you have created. You can recover your assets by **reconnecting the device via Bluetooth.**

When you tap the "Delete" button, you will be prompted to authenticate with either your **6-digit mobile app password or biometric verification** to proceed.
