# Set Up Security Mesures

## Set up Wallet Security

KEYRING PRO Wallet offers users two security measures, which serve as the final step to verify that the person acting is the device owner.

* **Passcode**: Verification through a 4-digit passcode.
* **Fingerprint**: Verification via fingerprint. Please note that this feature requires a phone with fingerprint recognition support and that the user has already registered their fingerprint in the system. Additionally, the passcode must be activated before enabling fingerprint recognition.

To activate these security measures, follow these steps:

1. Go to the options menu.
2. Select **Security**. Note: If you haven’t backed up your files, the system will prompt you to do so before proceeding with security settings. 
3. Toggle **Turn Passcode** to **On**.
4. Set up your 4-digit passcode.
5. Confirm your passcode.

Once the passcode is activated, you'll see the **Turn Fingerprint** option. If you have already set up fingerprint recognition on your phone, simply enable it.

You can change your passcode anytime using the **Change Passcode** option.
