If both the password and the e-mail account were lost, use Contact Us.
Open the Scratch website and click the Sign in link — this is where a user enters their password to log in to the Scratch website. At the bottom-right of the login menu is a "Forgot password?" link, which directs you to a page where you can enter information to recover the forgotten password. Then there are two options: enter your username or enter the email address associated with it. Once the information is filled out, click the light-grey "Send me a password reset link!" button, which will automatically send an email in which you can reset and view your password. You can also press resend to resend the email. If you choose to enter your username, it will send the email to the linked email account, and vise versa.
