Logim screen

Hello, my name is Thaynara and I am new in Arduino. I have a problem. I'm doing a login screen, when the user enters the correct password it creates another page. For this, use an Ethernet module.
But when the user enters the correct password , keeps the field to fill the password, and then throws down the that should appear when the User validate the password.
