SETUP: 1. Add the "Unique Device Identifier" element to any page where you want device ID capability
2. The element is invisible and automatically generates a unique Device ID when the page loads
3. No action required - the Device ID is immediately available in workflows

WORKFLOW USAGE:
Access the Device ID directly in any workflow:
→ Element: Unique Device Identifier A
→ Data source: Unique Device Identifier A's device_id ✅

EXAMPLE WORKFLOWS:

Basic Device Tracking:
When Page is loaded:
1. Only when: Unique Device Identifier A's device_id is not empty
2. Create new Device:
  - device_id = Unique Device Identifier A's device_id
  - first_seen = Current date/time

User Registration with Device Link:
When User signs up:
1. Create new User (normal signup)
2. Create new Device:
  - device_id = Unique Device Identifier A's device_id  
  - user = Result of step 1 (User)
  - trusted = yes

Device-Based Access Control:
When User logs in:
1. Search for Devices where device_id = Unique Device Identifier A's device_id
2. Only when: Search result is empty
3. Show popup "New device detected - verify your identity"

RECOMMENDED DATABASE SETUP:
Create a "Device" data type with:
- device_id (text) - The unique identifier
- first_seen (date) - When first detected  
- last_seen (date) - Most recent activity
- user (User) - Link to user account
- is_trusted (yes/no) - Security flag

IMPORTANT NOTES:
- Device ID format: "device_[unique_hash]" (e.g. "device_1a2b3c4d5e6f")
- Same device = same ID across browser sessions
- Different browsers on same device = different IDs (expected behavior)
- Element is invisible - no visual impact on your page
- Uses only technical specifications - no personal data collected
- Consider mentioning device tracking in privacy policy for GDPR compliance

TROUBLESHOOTING:
- If device_id is empty: Check browser console for errors
- For testing: Use browser developer tools to verify element is present
- Refresh page if device_id doesn't appear immediately
