It looks like VeriSign is testing out a new RSA SecurID like 2 factor authentication application for BlackBerry. In case you don’t know this would secure your eBay, PayPal, or AOL account by requiring you to enter in your username, password, and a randomly generated 6 digit code from this application to login. This really secures your accounts and is a form of what is called 2 factor authentication.
Many people already have such a system to connect to their work VPN systems and such so it is nothing crazy new. Some websites have already been trialing just giving out the small key fobs that generate these numbers so a BlackBerry app just combines the two.
It does not look like they are accepting any more users into the beta program but hopefully the app will be out soon.

eBay and PayPal have distributed the key fobs that you mentioned as an optional method to increase authentication security. I have used one ever since my PayPal account was compromised several months back — what a nightmare! It took WEEKS to resolve $1600 in fraudulent payments, some of which were from my checking account.
