Customers can update an account regardless of whether they access the customer portal directly or from and external site.
When the PTA_IGNORE_CONTACT_PASSWORD configuration setting is enabled, customers who access the customer portal directly can update their account, including changing their password, as they normally do. To access the customer portal in the future, they must log in with their user name and new password. The new password will not affect their ability to log in through an external site with the setting enabled.
Customers who enter the customer portal from an external site using PTA can also update their account. Although their password is ignored when the PTA_IGNORE_CONTACT_PASSWORD configuration setting is enabled, they have been authenticated through their login to the external site. As a result, the customer portal allows them to update their account, including their customer portal password.
