In our scenario, we're working on a web application that helps clients to sell their used items online.

We've been asked to add some extra rules around the part of our system that authenticates users.

Right now, the system only checks whether a user was successfully authenticated:

const isAuthenticated: boolean = await userIsAuthenticated(username, password);

if(isAuthenticated) {

redirectToUserDashboard();

} else {

returnErrorOnLoginPage("Credentials are not valid.");

}
