If you happen to forget your password, it can easily be recovered.
To recover your password, click on “Sign in with Email Address” and enter your email address. Once you enter your email address, the game will request your password and below you will find the option “or click here to reset it”.
Once you select this option, a new one will be sent to the email address associated to the account.
You can also change your password once you have logged into the game in Account Settings.
