When you create your account, a password is automatically generated and emailed to the email address you entered.
This password is the only way to get access to the account tied to the email address you provided when you registered this account.
To make sure you can receive that email, make sure you enter a valid email address when registering. You need to be able to access that email address.
We recommend that you change your password to something else when you log in for the first time. Use a password that you will never forget.
The support team can't tell you your password if you lose it. The only way to resolve this is to request a new password from the in game log-in screen.
