A computing device can include a processor; memory accessible to the processor; a lithium-ion battery; a power interface; magnet control circuitry operatively coupled to at least the power interface for receipt of electrical power; and a housing for the processor, the memory, the battery, the power interface and the magnet control circuitry, where the housing includes a first shell, a second shell, and an electropermanent magnet assembly that generates a magnetic force that couples the first shell to the second shell, where the electropermanent magnetic assembly is controllable via the magnet control circuitry to decrease the magnetic force to decouple the first shell from the second shell.

Computing device

Access to a system is permitted by first polling a low-power device/connection on a user device for a low-power multifactor authentication (MFA), and; refraining from polling a high-power device/connection on the user device for a high-power MFA. An indication is received from a user that the user would like to access the system. The low-power MFA is identified via the polling of the low-power device/connection, and the user is authenticated via the low-power MFA. After authenticating the user via the low-power MFA, the high-power device/connection is woken and polled for the high-power MFA. The high-power MFA is identified via the polling of the high-power device/connection, and the user is authenticated via the high-power MFA. Access to the system is permitted when the user has been authenticated using the low-power MFA and the high-power MFA.

Dynamic multifactor authentication using low-power and high-power monitoring

One embodiment provides a method, including: monitoring, using an accelerometer integrated with an information handling device, gravitational acceleration experienced by the information handling device; identifying, based on the monitoring, a change in the gravitational acceleration from a first gravitational acceleration metric to a second gravitational acceleration metric; and adjusting, responsive to the identifying, a time-keeping standard referenced by the information handling device based on the second gravitational acceleration metric. Other aspects are described and claimed.
