PayPal has been busy behind the scenes with two new form-factors for our two-factor authentication security key.
We launched both a new physical form factor that is credit-card sized, as well as an SMS version of the key. The credit-card form factor is pictured here. So far so good on the credit card and I find it a little easier to keep track of than my previous token.
