In the past Enterprise Mobility Management (EMM) has focused primarily on MDM, MAM and MCM. Recently there has been a lot of focus on the fourth pillar of EMM - Mobile Identity Management (MIM). This session will cover the primary use cases and discuss current solutions available for managed/un-managed, internal/public and mobile/web apps for iOS/Android devices.

Minimal code change. Can be implemented now.
No code change. Best experience. Requires MDM.
Cross platform. Open Standard. Still in spec stage.
No code change. Limited App support.
Only works for enterprise apps.
Platform specific. Not available now.
