One of those things on the should-be-done-someday list. If you can’t live with the auto-generated restore password, shoot me a mail with your cloud user name to support at vorpx com. I can delete your account, afterwards you can create a new one with a freely chosen password.
The cloud password gets stored locally though, you don’t really need to remember it. So alternatively you could just make a note with the auto generated pw in case you need it after a future reinstall.
