Usernames and Passwords
Your username is your unique identifier and unfortunately can not change but you can change your Name in the preference section and the name can act as your display name.
In this section you can do a lot of things including changing your current password and exporting your community data.
This data includes every thing that you ever posted or submitted on our website.
Our developers are working on a two factor authentication system where you can securely lock your account from intruders.
