Claim 6:
7. A method comprising:
receiving, by a processor device, prior proximity information from a first user device of a user, the prior proximity information indicating a first set of wireless network devices in a wireless range of the first user device during a set-up phase;
authenticating, by the processor device, the user to access sensitive information by a first factor authentication process; and
subsequent to authenticating the user via the first factor authentication process, and prior to granting the user access to the sensitive information, performing, by the processor device, a second factor authentication process involving:
receiving current proximity information from a second user device of the user, the current proximity information indicating a second set of wireless network devices in wireless range of the second user device during the second factor authentication process;
determining a level of closeness between the current proximity information and the prior proximity information;
determining that the level of closeness is a third level of closeness that is less of a match than a first level of closeness and a second level of closeness; and
in response to determining that the level of closeness is the third level of closeness, deny the user access to the sensitive information.
