I am not 100% sure of your question, but I will explain the websites passwords.
There is only one password needed for the website and that is the password you used to logon with.
Our website is using Community Builder ( CB ) as the main component for userid and passwords. The Forum is integrated into CB and as a result does not require a different password.
When you go into your profile there is a screen that allows you to change your password. You do not have to change it if you are happy with the password you have.
The following is a screen from Community Builder.
If you wish to change your password reset it here.
