Classification: CPC H  G | IPC G  H

Claim 0:
1. A system comprising:
a processor device; and
a non-transitory computer-readable medium comprising instructions that are executable by the processor device for causing the processor device to:
receive prior proximity information from a first user device of a user during a set-up phase, the prior proximity information indicating a first set of wireless network devices in a wireless range of the first user device during the set-up phase;
generate a fingerprint associated with the user based on the prior proximity information;
store the fingerprint for subsequent use in a second factor authentication process;
subsequent to the set-up phase, authenticate 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, perform the second factor authentication process, the 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 first level of closeness; and
in response to determining that the level of closeness is the first level of closeness, granting the user access to the sensitive information.
