Abstract: In aspects of user authentication facilitated by an additional device, a computing device can maintain authentication data usable to authenticate a user to use the computing device. The computing device implements an authentication control module that can determine an additional device is equipped to facilitate authentication of a user to the computing device. The authentication control module can then receive additional authentication data associated with the user from the additional device, and authenticate the user to use the computing device based in part on the additional authentication data received from the additional device.

Abstract: A computing device supports the use of multiple different authenticators for a user to unlock his or her computing device and access his or her user account. An authenticator refers to something that the user knows or has that can be compared to known authentication data in order to authenticate the user. In one or more embodiments, the behavior of the computing device varies for different authenticators by displaying user-selectable content in different visibility modes based on which authenticator is used to authenticate the user. In one content visibility mode content is fully visible on the computing device display screen, whereas in another content visibility mode content visibility on the computing device display screen is reduced. Additionally or alternatively, the behavior of the computing device varies for different authenticators by using different authenticators for different contexts of the computing device.

Abstract: Techniques for authentication for key access are described. In the described techniques, interaction between a client device and an assistant device is utilized to authenticate the client device for access to protected functionality and/or content. For instance, proximity between the client device and the assistant device, and physical authentication of a user with the assistant device, are leveraged for authenticating the client device for access to the protected functionality and/or content.

Abstract: Content visibility on a computing device is controlled based at least in part on the current location of the computing device. When the current location is a safe location for making user-selectable content visible on a display screen of the computing device and the computing device is unlocked, the computing device operates in a full content visibility mode. In the full content visibility mode all user-selectable content on the computing device is accessible to a user of the computing device. When the current location is not a safe location for making user-selectable content visible on the display screen, the computing device operates in a reduced content visibility mode. In the reduced content visibility mode content visibility on the display screen is reduced, such as by limiting which applications (e.g., application icons or widgets) are displayed or otherwise accessible to the user.

Abstract: In aspects of shareable devices, a shareable device has a memory to maintain identifiable information usable to identify users of the shareable device for subsequent reference. The shareable device implements a device sharing module that can receive the identifiable information about a user who initiates using the shareable device, and initiate an interactive session allowing a user to access the shareable device responsive to receiving the identifiable information about the user. The device sharing module can then communicate the identifiable information to an additional device that maintains the identifiable information for subsequent reference, and subsequently end the interactive session, thereby enabling the shareable device for use by a subsequent user. The device sharing module can also receive a disable command from the additional device to initiate disabling the shareable device.

Abstract: In aspects of a foldable display viewfinder user interface, a wireless device has a rear-facing camera to capture digital images, and has a foldable display screen to display a viewfinder user interface in which a camera preview image as captured by the rear-facing camera is displayable. The wireless device implements an image viewfinder module that can determine a semi-folded state of the foldable display screen, and the viewfinder user interface can be displayed on an approximate half section of the foldable display screen in the semi-folded state. The image viewfinder module can determine that an upper display section of the foldable display screen is not viewable in the semi-folded state of the foldable display screen, such as based on a camera image view from a front-facing camera, and the viewfinder user interface can then be displayed on a lower display section of the foldable display screen in the semi-folded state.

Abstract: A wearable device enables access to VPN endpoint devices for secure data communication and privacy for a computing device. The wearable device stores VPN configuration information for a user, which includes the user's VPN credentials for each of one or more remote VPN endpoint devices. When the wearable device is in close proximity to a computing device and is being worn by a user that is authenticated to at least one of the wearable device and the computing device, the wearable device communicates the configuration information to the computing device. The computing device can then use this VPN configuration information to establish a VPN connection to a VPN endpoint device.

Abstract: In aspects of shareable devices, a shareable device implements a device sharing module that can maintain an interactive session of a user on the shareable device. The shareable device can detect that the user has moved away from the shareable device during the interactive session, and obscure personalized content associated with the user who has moved away from the shareable device. The device sharing module is implemented to detect, without user input, a user condition indicative of an intent to end or share the interactive session. The device sharing module can determine a status of an executing application associated with the interactive session of the user. The device sharing module can then end or share the interactive session based on the detected user condition and the determined status of the application.

Abstract: Techniques for authentication for device access are described. In the described techniques, interaction between a client device and an assistant device is utilized to authenticate the client device for access to protected functionality and/or content. For instance, proximity between the client device and the assistant device, and physical authentication of a user with the assistant device, are leveraged for authenticating the client device for access to the protected functionality and/or content.

Abstract: In aspects of shareable devices, a shareable device implements a device sharing module that can recognize a user intends to claim the shareable device for temporary use. For instance, the device sharing module can determine that multiple users are present within a distance threshold of the shareable device and identify one of the users as intending to claim the shareable device. The device sharing module can then authenticate the identified user to the shareable device, without requiring user input, to enable claiming of the shareable device. The shareable device can obtain personalized content associated with the identified user for use on the shareable device. The device sharing module can then establish an interactive session which enables the identified user to access the personalized content through applications and services available on the shareable device.

Abstract: An electronic device includes one or more sensors to determine when the device is in use (e.g., being held or worn by the user) and when the device is not in use (e.g., is in a pocket or purse). Examples of such sensors include a capacitive sensor, a thermal sensor, a light sensor, etc. The device can be placed in a mount that allows the device to be more easily worn by the user. The mount extends the capabilities of the sensors on the device so that the sensors on the device can sense information through (or notwithstanding) the mount. The mount also optionally changes the viewpoints of one or more of the sensors, such as by re-directing a sensor that points to the side of the device so that rather than sensing information at the side of the mount information at the bottom of the mount is sensed.
