Use your normal account login name and password. No 'P' prefix or @rahul.net or other domain part is used. E.g., a user with email address 'joeuser@rahul.net' would log into the billing system as the user 'joeuser'.)
If you get an authentication error or other login failure, it probably means we have not enabled access for you. Simply send a request to support@rahul.net, mention your login name, and ask for access to our billing system. Username: Password:
