Thanks a mil, I will def help you with some :+1:

So what I am trying to accomplish is the following-

1-I want a user to register, and after the registration, they need to be redirected to another screen. Also, the app needs to look if the user email is already in use.

2- If the user wants to log in the next time, then I need the app to have a look and see if the user is already registered and then log them in

This is the basic I need to accomplish, there is some other features I need

I did have a look at the video's you send, But I do not understand the language. I can try doing what he is doing, but I won't know what I will be doing. I need to understand what he is doing.

This is what I have so far, this works to create the user and it does show in my Firebase Authentication tab. What I need now is for the app to be able to find the registered user and then log them in and take them to another screen.

This is Free Extension

1-I want a user to register, and after the registration, they need to be redirected to another screen. Also, the app needs to look if the user email is already in use.

this should be automatic directly from Firebase Auth

2- If the user wants to log in the next time, then I need the app to have a look and see if the user is already registered and then log them in

For what you need an application to check users who have signed in, you can immediately see from your firebase like this

In the Firebase Authentication tab it shows the client did register, but how do I get MIT App Inventor to go have a look if the details are in the Database corresponds with what is typed in so the user can then log in. This is my design screen.

If you want to get details of what the user is writing you can use FirebaseDB for the register and login, like this video


And you can see your user profile like this

I did follow this tutorial on the app, it works to register and to login, but there is a problem in the code somewhere, I can use anything to sign in, even if the user did not register.

the way to prevent users from logging in with someone else's gmail is to combine gmail and password, like this

Okay, I understand

How dit you setup your variable? Get tag and get value.....

that's my logic, so it's up to you to use a different logic. whatever logic is important is successful

Okay, I have set up similar blocks with some extras. Please if you can set up the same way and have a look where I went wrong.

for what you create variable IDnumber and password. please try to removing that variable.
I hope after you delete that variable, it might work and whether you have changed the rules on firebase to true

I have made the following changes just like you said:
