Conditional pages

[G73262R]

I am new to budibase, I have a few questions and hoping someone can give me a little advice or get me going in the right direction -

1. I noticed that user sign ups and logins are via budibase database where they are stored as "app users". Is there a way around that where I have a way of signing up users and storing the user info in my own database that I'm connected to or something outside the app itself?

2. When a user logs in for the first time, I want to have them fill out personal details before they can access any pages. How can I acheive that? Is there some sort of conditionals I can use that prevent them from seeing and/or accessing other pages until a form is filled out?

3. I want to build a client portal that is specific to each app user. Eg: the data displayed is only pertaining to their app user account which I hope to have some way to store in my database. Is there a way to achieve this? So far the only way I've gotten that to work is via queries that use views with a condition, but not sure if this is the right way to go about it?

Any help is appreciated!
