A communal computing device such as an interactive digital whiteboard can provide progressively more access to functionality and data on the device based on a level of certainty in the identity of a user. If a user is identified based on one or more low-fidelity identification signals such as an image of the user or a device identifier, the communal computing device may provide a first level of functionality that is limited. If the user requests greater access, the communal computing device can request that a trusted cloud-based provider authenticate the user by way of a personal device, such as a smartphone. The authentication may be a password or high-fidelity biometric identification. The cloud-based provider communicates successful authentication to the communal computing device and it, in turn, provides the user access to higher, second level of functionality. 诸如交互式数字白板的公共计算设备可以基于用户身份的确定性水平，渐进地提供对该设备上的功能性和数据的更多访问。如果用户基于一个或多个低保真标识信号(诸如用户的图像或设备标识符)而被标识，则公共计算设备可以提供受限制的第一功能性水平。如果用户请求更大的访问权限，则公共计算设备可以请求受信任的基于
