Use Users Setting field (username) in another view

[dherly]

I've created this app, and the initial view displays the User Settings screen to prompt for the username and password, which are related to the 'Users' table with columns ID, User, and Password. Once the user successfully logs into the app, a 'Register' view appears where the user must fill in the Date and Number of cars, but in field UsersWhoRegister must be autocompleted with the user who logged in. How can I achieve this?

Hi dherly,

This is a very bad idea. The credentials your users will use will absolutely not be secured as you will have direct access to them. 

You need to know : Will your app be public or private ? The difference lies in how the app will be used and the pricing. Public : fixed app price per month, private : license/month per user .If the app is public, no personal or important information should be available. More info here.

If you want your users (on a private app) to only see their related data, please check this thread.

Basically, you'll need to create an User table, and filter the data through the current user email. For example (tere are other ex. in the thread) : any(select(Users[Email],[Email] = useremail() )) will select the current user, and you'll be able to put that condition in every parts of the app (for example, showing the records related to the current user email). 

Be carefull as the method you're trying to implement will not comply to gdpr rules.
