Besides your email Windstream address, you will also need to enter your secret word or password. Using the wrong password or user name may result in your account not being registered. If this happens, contact your Windstream customer service. Most likely, you can resolve your problem by upgrading your browser. And remember to check the email address and password regularly to prevent your account from being suspended or terminated.
