PayPal has introduced a Security Key, a device that generates a new personal key every 30 seconds. Use of this should make your account much more resistant to unauthorized access. I signed up for mine last night.
More info at PayPal. Try Help "security key". Sign up at My Account/Profile/ Account Information.
While signing up, I noticed a button that said something like "use this thing with eBay, too".
Any AW user have experience with this? Any problems?
