I've got a new phone. Do I need to sign up to MarvellousMe again?

No. If you change your device, just:

  1. Download and open the MarvellousMe parent app
  2. Tap 'Log in'.
  3. Enter the email and password that you used when you signed up to MarvellousMe.

As you have already signed up and created your account in MarvellousMe, you do not need to renter your parent join code.
