To recover your password open the app and click on “Log in with your email address" and enter the email address you used to create your account. After you enter it, click on "Ok" at the top right corner of the screen. After you do that, the game will ask you to enter your password and, below, you'll find the message "or click here to recover it".
At this point, you'll receive an email with a new password, which will allow you to log back into your account.
If you misspelled your email address or if you can no longer access that email account, please contact us so that we can set up a new password for your account.
