Firebase, AirTable and Bravo

At the moment I have FIrebase dealing with logins, Aurtable for the Database and obviously Bravo for the app.

Currently, if I log in or register there's no validation step and people can just get into the app without a validation step, which is an issue.

Secondly, I haven't got Firebase and AirTable talking, so when someone registers, when you get into the App, Airtable and Bravo assumes you're the only user, and anything the user submits is visible to anyone using the app, instead of just that user.

I'm not sure how to tackle these issues, or if any of the new features might offer previously unavailable solutions.

Also, I've used the picture [component:input-image] so users can add their own profile pics inside the app.  How do I get this information over to AirTable so I can populate other pages with the profile picture?

And one more; so a user logs in, and they can create their own profiles; but when profile is selected, I want the details for that specific profile to populate other pages until a different profile is selected.  

So for example:

            PROFILE 1 - SUB PAGE PROFILE 1
USER - PROFILE 2 - SUB PAGE PROFILE 2
            PROFILE 3 - SUB PAGE PROFILE 3

These profiles would have their own profile pictures and options.

Sorry, that's a lot of questions all in one go!

Any ideas? 🙂
