The code is more for the nerds, but, the idea is probably best expressed differently. Maybe its best I paint a possible scenario.

You go into your app store, google or apple, and you see Snapie - Chat with people around the world, make friends, earn crypto. You download this app. You know nothing.

You see: Login with Google.

You walked through the door.

Right now... people would download the app, see: Enter POsting key only. Their face like those confused puppies. sideways look

Ideally the best onboarding happens one to one, but its not as fast. It scales if you make more of you, more onboarders, but no onboarder on his/her own hasd the reach of an app store.
