Once again, we learn that authentication based on sight alone is not the only game in town. A company called PhoneFactor delivers a two-factor authentication scheme in which the second piece of authentication material is literally your telephone. In simple terms, here’s how it works:
- Supply your traditional username and password as prompted.
- Your telephone rings.
- Press the pound sign!
- That’s all there is to it!
The potential of this solution to deliver security while ensuring accessibility for people with disabilities simply can’t be ignored!
