If you forgot your Password you must click the "Forgot Password" string on the V4S Kiosk Login screen. Then the pop up shows up the App Key and Email ID you have entered on the login screen with Cancel and Ok button.
If you are not able to view these details on the pop-up, that is because you have increased the default font size on your Device.
As there is no scroll option on the forgot password popup, you are not able to view email Id, Cancel or OK buttons.
Please reset the font size on the mobile from settings Tab to lesser size and then reset the password for V4S Kiosk. Once you have reset the password you can again change the font size to small, medium or maximum if required.
