@AARPCaroline
Well, I'm glad to hear there hasn't been a breach. However, I would like to stop going in circles about how this is supposed to address the 2 issues:
(1) protecting my account
A one-time text/call to an arbitrary phone number given on some web form is not a proper authentication of anything. A malicious person can enter anything there. If they borrowed a friend's phone, or bought a cheap pre-paid, it would not prove identity.
(2) preventing multiple accounts
Pretty much the same issue. Again, the borrowed/purchased phone applies here. Not a secure authentication. Checking for accounts being accessed from the same internet location is a first better check, although it can be avoided with a VPN.
If a secure authentication has to be done on a one-time basis, it must deal with more information than just some phone number! If AARP is truly concerned about securing accounts, there should be an option for modern mechanisms, such as 2-factor authentication AT EACH LOGIN.
Please have someone provide a better description of how this is supposed to be secure with the one-time phone text/call. I'll gladly talk to them offline about the situation. Just don't talk about security then do virtually nothing.
@AARPCaroline - Sorry for the long rant, stuff like this just gets my goat. Maybe its due to the work I'm in.
Cheers,
Ray
