Abstract
This disclosure describes techniques for selectively providing access to a physical space. An example method includes identifying a location of a device associated with an authorized user based on an electromagnetic signal received by at least one sensor from the device. The electromagnetic signal has a frequency that is greater than or equal to 24 gigahertz (GHz). The example method further includes determining that the location of the device is within a threshold distance of a location of a threshold to a secured space and determining that an authentication score indicating that an individual carrying the device is the authorized user is greater than a threshold score. The authentication score is associated with multiple authentication factors identified by the device. Based on determining that the authentication score is greater than the threshold score, the threshold is unlocked and/or opened.
