Q & A

What is the main purpose of the app being developed in the video?

The app allows both admin and user roles to log in through the same login screen, but they are redirected to different screens based on their role.

How does the login system differentiate between admin and user roles?

After logging in, the system checks the user's role and redirects them to the admin screen if they are an admin or to the home screen if they are a regular user.

What is the role of Firebase in the app?

Firebase is used for user authentication in the app, allowing users to sign up and log in. Additionally, admin users can fetch and edit data from Firebase based on a user's email.

What is a key feature that the admin role provides in this app?

The admin can access, edit, and manage user data by entering the user's email. The admin also has the ability to create new users and deactivate existing users.

What precaution does the developer mention about editing user data?

The developer advises against changing a user’s email because it could break the authentication process if using the same login method as demonstrated.

Why does the developer recommend not saving user passwords in the app?

Saving user passwords can violate user privacy. The developer only does it for educational purposes in this video but doesn't recommend it for actual use.

How does the admin create new users in the app?

The admin creates new users by filling out forms with at least an email and password. A button is then used to add the new user to Firebase Authentication.

Why is it important for the admin not to change a user's password from within the app?

Changing a user's password via the admin controls will not affect the Firebase authentication password, making the change ineffective.

What is the role of the splash screen in the app?

The splash screen checks whether the user is an admin or a regular user and redirects them accordingly to either the admin or home screen.

Can the admin deactivate users in the app, and how is it done?

Yes, the admin can deactivate users, but this action must be done through the Firebase Authentication console, not directly in the app.
