Dual Factor Authentication using your phone

PhoneFactor makes a product that uses your phone instead of a key fob for tokenless dual factory authentication.     In my opinion this is a much better and cheaper way to manage secure authentication than having to purchase and maintain key fobs that can easily get lost.

PhoneFactor can work in three different ways to authenticate.

1.  Phone Call:   Calls your phone and enter your pin number.

2.  Text message:  Text your phone and reply with pin number.

3.  Voiceprint:  Calls your phone and authenticate by speaking your passphrase

The best part is this product is FREE for companies with up to 25 users.

They also offer a Standard and Enterprise version that integrates with products like Outlook Web Access, Citrix, Terminal Services, and RADIUS applications.
