## 7.2. Protecting Access for Mobile Users

You must give users access to your organization's resources while they are on the go. At the same time you must manage risk. OpenAM supports risk-based adaptive authentication, device fingerprints, one-time passwords and other multi-factor authentication capabilities that help you do both. As OpenAM handles authentication through plugin modules that you can chain, your OpenAM service can meet a variety of requirements.

OpenAM's Adaptive Risk authentication module lets you add risk assessment to any authentication module chain, dynamically requiring stronger authentication when circumstances require it (new location, ancient last login time, new device, new IP address, specific application, and so forth). You can add the Device Print module to an authentication chain to fingerprint users' devices for additional risk assessment, making it easier to handle sign-on when users bring their own devices.

OpenAM also lets you decide exactly what stronger authentication means in your situation. You can for example add multi-factor authentication involving mobile devices using OpenAM's OATH and HOTP modules either to use a one-time password soft token generated on a device, or to send a one-time password in a text message to a mobile phone.

In addition to capabilities supporting new applications, OpenAM integrates well with existing systems needed by users on the move. Whether users are authenticating from a mobile device through a gateway using an MSISDN, starting single sign-on by logging on to a laptop, or connecting to a VPN with certificate based authentication, OpenAM has an authentication module for that.

All of these capabilities are available with OpenAM out of the box.
