Got an email this morning from a friend who has recently started a new service: authentication via caller ID.

Basically if you need to get to a private page of a site, you call a number from your cellphone when prompted and the system lets you in. Since the call is not answered (all the system has to do is check that a call was coming from your number) it's free.

Beautiful in its simplicity. More information on SAINTlogin.
