PayPal to issue Password Key Fobs

This is big news.  EBay will offer password key fobs to users.

PayPal has nearly 123 million accounts

eBay is getting ready to offer its PayPal users a password-generating key fob that promises to increase the security of the online payment service.

The device displays a new one-time password in the form of a six-digit code about every 30 seconds. PayPal clients who opt to use the device will enter this password along with their regular credentials when signing into the service. The key fob is meant as another weapon in the battle on data-thieving phishing scams.

The password-generating device is based on technology from VeriSign, with which eBay entered into a security partnership in 2005. Such key fobs are also used for added security by large corporations for access to corporate resources, and some banks and brokerage firms offer them to clients with a high net worth. Other companies that supply the password gadgets include RSA and Vasco.
