Verisign now have a two factor tool for mobile phones. Use the Market or App Store and search for Verisign. The app is called VIP Access.
Two factor is often seen in corporate environments by means of a random number generating keyfob, token or card.
This will quite simply give two factor authentication to your PayPal and eBay accounts. In my opinion if you’re not using this on your PayPal account you *really* need to reconsider your financial security online.
