From login page, you will match login/pass with stored parametners, if match found, you will store in tinyDB that this user IS_LOGGED_IN True.



but, my logout button is on another screen ( screen2) .... so how I will get TinyDB1 in login screen ( screen2)..?

anyone know? what to do if I want to add multiple users system..

I want to add multiple users login system and after any user log in they go to another screen and keep users logged in always until they clicking on logout button. then after clicking they will back to the login screen again...

now my problem is what should I put in the empty place....

How many users are you planning to have, bearing in mind that it is recommended to stay below 10 real screens?

You could use a virtual screen (vertical arrangement) generated with a dynamic components extension....
