# MFA Settings & Autolock

Kastle includes built-in security features to help keep your funds safe at all times. These settings include:

* **Auto-Lock** – Automatically locks your wallet after a short period of inactivity.\
  👉 For maximum protection, we recommend setting Auto-Lock to **no more than 1 minute**.
* **Biometric Authentication** – Use your fingerprint or face ID for quick and secure access.
* **Fallback PIN Code** – A backup method to unlock your wallet if biometrics are unavailable.

You can manage all these options from the **⚙️ gear icon in the top-right corner** of the dashboard.

⚠️ **Security Tip**\
Do not rely on the **PIN code alone**. The PIN is only a fallback — enabling **both Auto-Lock and Biometrics** gives you the strongest protection against unauthorized access.
