Entrust IdentityGuard
Entrust has introduced IdentityGuard, a very lightweight (paper based) approach to two factor user authentication.
With Entrust IdentityGuard, users continue to employ their current user name and password, but are also provided with a second physical form of authentication based on an assortment of characters in a row/column format printed on a card. A user must successfully complete a coordinate challenge to demonstrate that they are in possession of the appropriate card.
