+## 🔒 Security
+
+The **Security** tab in OpenSign (found under **Settings > Preferences > Security**) allows users to manage key authentication methods to protect their account access.
+
+### 🧩 Features Available:
+
+#### ✅ Two-Factor Authentication (2FA)
+
+Enhance your account security by enabling 2FA. Once activated, you'll enter a time-based code from an authenticator app each time you log in.
+
+#### 🛡️ Passkey Authentication
+
+Passkeys offer a **passwordless**, **phishing-resistant** login experience using your device’s built-in security features such as fingerprint, Face ID, or PIN.
+
+👉 For full details on setting up **Two-Factor Authentication (2FA)** and **Passkey Authentication**:  [🔒 View Security Setup Guide](https://docs.opensignlabs.com/docs/help/Settings/SecurityManagement)
