Abstract: A multi-user aware (“MUA”) computing device, such a communal computing device like an interactive digital whiteboard, can enforce role-based constraints on the modification of components, such as configuration settings. The MUA computing device can be configured with universal settings, global settings, and temporal settings. Universal settings cannot be changed by users of the MUA computing device. Device owners can change global settings that apply to all users of a MUA computing device. All users of the MUA computing device can change temporal settings. Changes to temporal settings are stored in profiles associated with authenticated users but are not persisted for guest users. When all users have stopped using the MUA computing device, the device can be configured with default values for the temporal settings in order to return the device to a known state.

Abstract: Techniques and apparatuses for a dynamic face and voice signature authentication for enhanced authentication techniques are described herein. In one or more implementations, an authentication system is configured to authenticate a user using a combination of voice and facial recognition techniques. The authentication system supports multiple phrases per user, such that the user can use different phrases to gain different types of access to a device or resources. Doing so provides enhanced customized access to the device or resources.
