Adding a pin number to a Supp Card

[whatmeworry]

I noticed from August 1, all credit cards need to have a pin number.

My question is, how do I add pin number to a Supp Card, in particular an Amex card? Do I just need to add the card online or do I need to call up Amex?

I think each supp card member can set up their own login on the Amex website for their personal card on your account. Log in as them and they can click on Manage My PIN
