how can I create a login page and bind it with an appropriate managed bean for logging, I am building an ADF app, I am connected to the HR database schema

this is what i am supposed to do, I built the pages but here's what I have on my mind:
I add the managed bean, generates class automatically, add parameters and accessors and login method as following
public String login() {
// Implement your login logic here
if (username.equals("validUsername") && password.equals("validPassword")) {
return "success"; // Navigation outcome
} else {
// Display error message
FacesMessage message = new FacesMessage("Invalid username or password");
FacesContext.getCurrentInstance().addMessage(null, message);
return null;
}
and then edit the page values and all like this

but I am not sure what is the right thing to do next, or if I am not building it right
and if using a router like this will make it better
