## When to use this skill

**ALWAYS use this skill when the user mentions:**
- Biometric authentication (TouchID, FaceID, fingerprint)
- Securing sensitive actions with biometric confirmation
- Fallback when biometric hardware is unavailable

**Trigger phrases include:**
- "biometric", "Face ID", "Touch ID", "fingerprint", "biometric login"

## How to use this skill

1. **Install the biometric plugin**:
   ```bash
   cargo add tauri-plugin-biometric
   ```
2. **Register the plugin** in your Tauri builder:
   ```rust
   tauri::Builder::default()
       .plugin(tauri_plugin_biometric::init())
   ```
3. **Configure capabilities** in `src-tauri/capabilities/default.json`:
   ```json
   { "permissions": ["biometric:allow-authenticate", "biometric:allow-status"] }
   ```
4. **Check availability and authenticate from the frontend**:
   ```typescript
   import { authenticate, status } from '@tauri-apps/plugin-biometric';
   const bioStatus = await status();
   if (bioStatus.isAvailable) {
     await authenticate('Confirm your identity', { allowDeviceCredential: true });
   }
   ```
5. **Implement fallback** for devices without biometric support (PIN or password entry)
6. **Pair with stronghold plugin** for unlocking encrypted secrets after biometric confirmation

## Outputs

- Biometric authentication flow with availability check
- Fallback strategy for unsupported devices
- Integration pattern with secure storage
