Step 1: Check the error message:
If it starts with "You have entered an invalid username or password" go to Step 2.
If the message ends with "Please contact the CSD Helpdesk via email or at 310-630-2300 if you need access to the PiP." Contact the CSD Helpdesk via email or at 310-630-2300 and tell them your PiP account is INACTIVE.
Otherwise contact the CSD Helpdesk and explain what happens.

Step 2: Check your Username and Password:
Your username is only letters, no \ or @. The password contains at least 7 characters, including at least one capital letter and one number.
If you are a group user, try http://PiP when you are on the Optum network. If you are a group user with an HCPWEB account for the external PiP, remember username and password can be different than your Optum account.
Contact the CSD Helpdesk via email or at 310-630-2300 and ask them to RESET your HCPWEB password.
