There is now an Apple iPhone application available called VeriSign which will generate a password for the iPhoners PayPal, eBay and AOL accounts.

VeriSign for the Apple iPhone is optional and free to customers, however if you sign up no one else will be able to access your account without your password, user ID, and a 6 digit number generated by the Apple iPhone according to a report by bits.blogs.

This app comes via VeriSign who have been offering ID services based on key chain sized hardware for roughly 3 years. VeriSign is trying to serve banks and consumer orientated websites that need extra verification for customers.
