If you are looking to retrieve your username or password, you can do so by clicking either 'username' or 'password' next to "I Forgot Username / Password" at the login screen.
This will bring up a page asking you to enter your email. Please be sure to enter the email that is attached to your MV account, most likely the email you used at signup.
The username or password will be sent to that email.
If you no longer remember the email attached to your account or no longer have access to that email, reach out to us at email@example.com letting us know the situation and we'll let you know what we need to locate your account and verify you as the owner to make sure you have access.
