I just saw an article that Verisign now has a free iPhone app offering two-factor authentication:
The security app offers two-factor identification designed to strengthen protection on e-commerce site and with other online accounts. As of today’s launch, Verisign (NASDAQ: VRSN) said it has signed up over 40 Web sites as participating members of its VIP Network, including eBay (NASDAQ: EBAY), PayPal and AOL.
I personally think this is a great thing. I previously used a Verisign token to protect my OpenID account at pip.verisignlabs.com. It was always a pain in the you-know-what to carry around, so I never extended it to be used with my PayPal or Ebay accounts. I ALWAYS have my handy iPhone nearby, so I immediately downloaded the app, activated it, and tied it to my PIP account. It worked like a charm. Next is setting it up with paypal, ebay, etc.
Anyone else have experience with these virtual tokens? Any cons that I should be aware of?
