Secure Storage Login Capability

Good Day,

I want to create a very basic app login hence I am looking for alternatives to OAuth, Token Auth etc. I just want a login page with a Username and Password. That's it, nothing else. Therefore, I decided to use Secure Storage with the thought process being.......a username and password is stored by a user initially. When the user opens the app in the future, they enter the same user name and password and hit 'Login'. So, this login checks the keychain to ensure the password is correct and then allows access to the app by opening a new window. 


I modified the Secure Storage code to include a 'Login' Button however nothing happens when I hit Login. Therefore, I assume that the problem lies with the Login button. Can I be guided on how to fix this? Thank you. Below is the code:

                //Click on the button to store key and value in the keychain
                Button {
                    id: saveButton
                    text: qsTr("Save Data to Keychain")
                    onClicked: {
                     SecureStorage.setValue(username.text, password.text)
                Button {
                    id: loginButton
                    text: qsTr ("Login")
                    onClicked: {

                            var window = component.createObject (root)
