If you can't remember your password for your Marvel account, you can reset it:
- Head to Marvel on the web and hit the login button
- Click on the 'forgotten password?' link
- Enter your email address and hit the 'reset password' button
- You'll get an email with the reset instructions. If this doesn't come through within a few minutes, check your spam folder
Note - if you normally login to your account using Google Drive or Dropbox, you won't be able to reset your Google Drive or Dropbox password using this option.
