Create App on Blynk and deploy to all family devices

Hi new to Blynk but concept seems great.

If say I have an ESP8266 controlling front for light via relay, wire a Blynk app and worked fine, how can I deploy this app to SL family member devices without having to retire the app on each device and not login with my credentials??

Here is what you need. Easy as 1-2-3:
