A device may determine that a user device should be authenticated; and determine a confidence measurement based on an established activity pattern of the user device. The confidence measurement may relate to a likelihood that an authorized user of the user device is in possession of the user device. The device may authenticate the user device based on the confidence measurement.

User authentication based on established network activity

A user device may identify a received a signal indicating an incoming call; determine that another user device has answered the call; generate call log information that indicates that the other user device has answered the call; and store or output the generated call log information. Additionally, or alternatively, a set of user devices may receive a ring signal indicating an incoming call; a particular user device, in the set of user devices, may answer the call; and another user device, in the set of user devices, may store a unified call log. The unified call log may indicate that the particular user device answered the call, and may further indicate that the other user device did not miss the call.
