Online payment service PayPal, a subsidiary of eBay, rolled out on
Friday a second factor for authenticating users online — a key fob
that generates a pseudo random security code every 30 seconds.

Following a beta program launched at the RSA Security conference
in February, the service is now available for both eBay and PayPal
customers, the companies said in a statement. The security token,
produced by security-services firm VeriSign, generates a pseudo-random
six-digit number every 30 seconds that can be authenticated through
VeriSign’s Identity Protection service.
