Sunshower.io is a little different from a lot of similar products on the market in that it is entirely self-serve. To begin, simply go to https://sun.sunshower.io/stratosphere/#/signup. Enter your username, an e-mail address that we can reach you at, and a secure password. If we can't reach you at your e-mail address then we won't be able to reset your password.
Your password must be at least 8 characters long. We recommend using https://lastpass.com or an equivalent service for additional security.
