Wito is an authentication mechanism based on phone call.

Nowdays there are several other products based on the caller ID identification, every one of them requires that the user calls to a phone number (commonly a toll-free number) to login towards a service like home-banking website.
Unfortunately this kind of authentication has a serious security issue: it's subjected to mobile impersonation attacks (based on spoofing of the caller ID), which lets an attacker make the service think that he's actually another person.

Wito is different. By changing the paradigm, it's totally immune from this vulnerability.

The mechanism works as follows:
The user fills the form with his  username and password.


At this moment the system immediatly calls the user, it's not necessary to answer because the calling number will be always the same apart from the last digits (e.g. the last four ones).

Th user has to simply type the last digits of the calling number, and he will by immediatly authenticated.
