Description
Multiuser mode allows multiple users to share a mobile device by providing a degree of separation between user data. To date, no mobile device with multiuser mode features meets DOD requirements for access control, data separation, and nonrepudiation for user accounts. In addition, the MDFPP does not include design requirements for multiuser account services. Disabling multiuser mode mitigates the risk of not meeting DOD multiuser account security policies.
