PayPal to combat phishing with keyfobs.

Ars Technica reports that "eBay subsidiary PayPal is preparing to offer secure key fobs. The devices, which display a six-digit code that changes every 30 seconds, will be made available free to all PayPal business users, and will cost $5 for all personal PayPal account users. Those who opt in on the key fob will have to enter the six-digit code when logging in to PayPal."
