-# 2. Select Go to applications
-# 3. Select your application
-# 4. On the left hand side menu, select Integrations | MQTT
-# 5. See Connection credentials
-# 6. For the password press button: Generate new API key
-#    Each time you press this button a new password is generated!
-#    The password looks like:
-#    NNSXS.XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
