+  ## Regenerate Device Token - Forbidden
+  
+    Tests that users cannot regenerate tokens for devices belonging to other users.
+  
+    **Expected Behavior:** Returns 403 Forbidden when trying to regenerate token for another user's device
+  
+    **Status Codes:**
+    - 403: Forbidden (device belongs to different user)
+  
+    **Use Case:** Verify authorization - users can only manage their own devices
+  
+    **Setup:** Use Bearer token from user A, try to regenerate token for user B's device
