Who here knows Customer Center logins very well? I have been doing an experiment before we implement SuiteCommerce Standard, to find out how logging in to NetSuite works for Contacts. I created 3 Contact records, each on a different company-type Customer, and gave all the Contacts the same email address, and the same password in their respective Customer's Access subtab. When I log in to NetSuite with that Contact's email address and password, it first has me choose which Contact I'm logging in as, out of the 3. If I change the password (but not the email address of the 3rd Contact (they are all each in different Customers by the way), then it keeps telling me the email address or password is wrong. I have triple checked and changed the password to make sure I wasn't just putting it in wrong. It also removed that 3rd contact from the options of who I can log in as when logging in with the old password the other 2 still have. This leads me to believe that a User is identified uniquely by using both the email address AND the password, and if either of those is different, it counts as a different user. BUT, I don't understand why if that is the case, I'm not being allowed to log in as the user whose password I changed, but whose email address is the same as the other 3. Does anyone know how to fix this problem, or if it's just not a supported use case in NetSuite?

Unsure if this helps, but from my experiences on the SuiteCommerce side if you set up a contact on two customers (either the same contact record or different contact record with same email), and assign both the same password, the contact is only able to log in to the customer that they were given access to first. If you give both contacts a different password, then using password1 would get you into the first customer, and then password2 would get you into the second customer. If the user decides to reset their password with the above scenario (where if they have two different passwords for two customer logins), then the password is reset for both accounts, and logging in with the new password will only allow a login to the customer account the user reset the password on. I've been trying to find a solution to allow some of our contacts who are associated with multiple customers to have access without multiple email/password combos, but with no luck. I think it's just not a supported use case.

What is your intended outcome? Do you want 3 contacts with the same email to access different accounts or do you want them to be different?

I'm just trying to find out what use cases NetSuite supports, but ran into a snag with testing it when I couldn't log in for the password-changed same-email use case.
