Hello friends

On my current project, there is a need to support multi factor authentication for our web site. For those of you not in the know, this means users always must provide three types (factors) of credentials to authenticate themselves to the site: something they have, something they know, and something they are. The idea is that adding each factor increases exponentially the difficulty of unauthorized entry into the account.

It should be noted that you can have more than these 3 factors, and this will add additional security. But at the very least, supplying these three fundamental factors should be a basis for your security model.

I have not always been directly involved (but have been involved with many of the design decisions), but the isuses involved are quite fascinating and I still wanted to share it with you, my faithful blog reader. By the way, the chief developer on this is Christian Jungers (I am not a representative or employee of CM3 Consulting, and my opinions do not necessarily reflect theirs, or theirs reflect mine.)


Thank for all friends
