Footnote:
You can change your password on the Account Management page, at
https://account.frogster-america.com/
If you do not remember your password for the account system (Because it can be different from your in-game one), click the "Forgot your PW?" link in the top right.
You'll need to input your registered e-mail, and a new password will be sent to you.
If you do remember it, and successfully log in, click on the "Game Accounts" tab, and click the "Change PW" link next to your in-game login.
You can also change your forum password from this page.
I would also advise that you
change your account system password,
especially if it's the same as your account password, under the "Personal Data" heading, "Login Data" sub-heading.
For maximum security, you can also
change the password on your e-mail account (varies by service provider) or change your registered e-mail.
If you no longer have access to your registered e-mail, please submit a support ticket, as you will need assistance to change your password.
