How to make a login screen without input bar and without having to press enter on password field?

Hi, I am really struggling with this because of the behavior of the PasswordFieldcomponent that won't let me retrieve the string if the user doesn't press done on the mobile keyboard.

Basically I need the PasswordField to behave like the Textfield component so that when the user touches the login Button my app can directly send both fields even if the user hasn't pressed done on the mobile keyboard.

Is there any way to make this happen ?

Edit : Right now I have this code which works fine in the editor but no on mobile

 public class Textfield : SquaredMenuElement, IMenuElement {
 
     public string defaultText = "";
     public bool isPasswordField = false;
     public static bool inputHidden = true;
     public GUIStyle style = new GUIStyle();
 
     public static Dictionary<string, string> textValues = new Dictionary<string, string> ();
 
     private string stringToEdit;
 
     protected override void Awake(){
         base.Awake ();
         stringToEdit = defaultText;
         TouchScreenKeyboard.hideInput = inputHidden;
     }
 
     void Update(){
         Debug.Log( gameObject.name + " : " + stringToEdit + " focus : " + GUI.GetNameOfFocusedControl() );        
     }
     
     void OnGUI(){
 
 
         if(!isPasswordField){
             GUI.SetNextControlName(gameObject.name);
             stringToEdit = GUI.TextField ( position, stringToEdit, style);
         } else {
             GUI.SetNextControlName(gameObject.name);
             stringToEdit = GUI.PasswordField( position, stringToEdit, '*', style);
         }
 
         if(GUI.GetNameOfFocusedControl() == gameObject.name && stringToEdit == defaultText){
             stringToEdit = "";
         }
         
     }
 
     public string GetText(){
         return stringToEdit;
     }
 }

The problem is, on mobile (android at least, didn't try ios), when I have two of my custom Textfield, whenever one gets the focus the value of the other is copied into it for some reason. Also this doesn't happen if you comment the line TouchScreenKeyboard.hideInput = inputHidden;
