In the newest firmware update, 2.2.5, you will be automatically prompted for a username and password when first trying to access a TPDIN-Monitor-WEB3. If you click sign in when prompted to put in a user name and password, and don't have a username or password set up, you will be allowed access to the device. Leave the username and password fields blank. When you do get a user name and password set up on your device, all you have to do is fill out the prompted username and password textbox and sign in to your device in the future.
