TextInput.Password field font

It was possible via lookandfeel/org.kde.breeze/contents/lockscreen/MainBlock.qml
to change input field look with:

@@ -59,6 +59,7 @@ SessionManagementScreen {
Layout.fillWidth: true


         placeholderText: i18nd("plasma_lookandfeel_org.kde.lookandfeel", "Password")                                                                                             
+         passwordCharacter: "\u200b" 

This made password to look “invisible” as in terminal password input instead of putting * for each pw character.

Could you please help me find where it is in the code now? I’m probably looking for source of TextInput.Password

It would make nice feature btw.
