Keeping your internet secure may require an occasional password reset. To change your Wi-Fi password, log in to My Account via the HTC homepage.
In My Account, click on Account Detail. When your details screen appears, find the Internet icon on the left-hand side. Click on the Actions button in that box, and scroll down to Manage My Wi-Fi. The new screen will give you the option to change your password or Wi-Fi network names. You can watch a step-by-step video, and learn more, here.
