Forget user login info in the Android App and need to pair again

Hi all, I am using U1 for a few months, and I want to add a new device to it. However, I have fogot the login information (both username and password!!). I would like to register a new user account, but it needs me to pair the U1 again. I would like to ask if I pair the app again with a new user account, will my U1 current configuration will be reset or it will load all current configuration to the new account?
