This is image of the component which used in my. You can use many components. And you can design your UI in your own way.
This is screen shot of Blocks ( Main Part of the App )
You can add many textbox but i only used 2 textbox.
And also i used notifier. When user will enter all the information and click on the Sign up btn. The notifier will notify user Scessfully Login.
Storing data isn’t hard but when you want to call the data from airtable then it will be a problem because everytime you want to call data you need to know exactly which column the data is because if you don’t then you will get random data.
I believe it cannot be accepted as complete guide . The above code which shows the value into airtable. As per this guide whenever you open the app, your input will be created and stored. No logics are used. But this is very very basic in airtable block.
You need to explain, what should happen for next time login
You should explain what should happen if I use wrong credentials
