Diners Club Club Rewards - Security questions coming?

I received a curious popup this morning when I logged in to my personal (professional) US-based account. It said that on January 29 (that's tomorrow, ie Sunday) "CAM users" (what in the world are those, in this context?) will need to set up secuirty questions, which may be asked on subsequent logins.

Security quesitons, I'm familiar with that, that I would understand if that's all it said.

But whether I am or am not a "CAM user", and why they are the only ones who will get security quesitons, that's what I have no clue about! :confused:

Extremely wild guess: Canadian American?

I've just logged into my [corporate] Diner's Club account online and got the above popup too. I wasn't asked to set up security questions.

Doesn't surprise me one bit. And I'm sure CS will have no idea either!

But whether I am or am not a "CAM user", and why they are the only ones who will get security quesitons, that's what I have no clue about! :confused:

Corporate Account Manager?? I think that's the name of the program my admin uses though, not "us" the cardholders.

I clicked on the Forgot user ID/password? link on the login page and found this -
Corporate Account Administrators:

I went to make a payment last week and had to create 3 security questions.
