To log into games, you use the account you created on the Aeria website. You can use the account you're posting with here to log into the game.

You log on with the same account and password as here on the website. If you forgot your password, go to the Aeria Website, log out off your account, click the log in option and choose "Forgot Password." Enter the e-mail attached to the account and follow further instructions sent to your e-mail to reset the password.

I have done it. Thanks i can log now

Have a good day ahead.
Godspeed !
God Bless !
