You can recover your username/password at your tennis center web site. Each site we support can have a few different recovery options, so it is best to look for the LOGIN function - and that function will have a 'forgot username or forgot password link for you to follow.
Many sites have a 'help' page specifically for the way they have chosen to implement the software. If you are having difficulty logging in, please check with your tennis center or tennis organization website for further instructions.
Alternately, you can have your tennis center rest your password. Tennis Center staff cannot lookup your password, but they can reset it.
