Traditional User ID and Password systems use static passwords that are vulnerable to many types of attacks such as fake web sites, virus and spyware through which the attackers can steal User IDs and Passwords. To alleviate this vulnerability, AT.Pass 4.0 employs the dynamic one-time passwords to authenticate users' identities.

The AT.Pass Mobile Token downloaded to your iPhone is your personal secure key to the AT.Pass-enabled application systems. These tokens are uniquely generated at the time of activation and they are user specific. No two users have the same token.

With this form of token, you can generate the one-time password (OTP) for authentication of your application systems.

Note: This application does not provide authentication to the iPhone itself. One-time passwords generated with this application can only be used to access those systems already integrated with AT.Pass 4.0
