1. A system for preventing unauthorized access, comprising:
one or more authorization processors; and
a memory in communication with the one or more authorization processors and storing instructions that, when executed by the one or more authorization processors, are configured to cause the system to:
receive an authorization request from a first user device to register the first user device to access an account;
scan the first user device to determine a first device fingerprint;
store the first device fingerprint to the memory as an authorization fingerprint;
receive a login request from a second user device that has not previously been used to access the account;
responsive to receiving the login request from the second user device, scan the first user device to determine a second device fingerprint;
determine whether (i) the first user device is within a predetermined proximity to the second user device and (ii) the authorization fingerprint matches the second device fingerprint beyond a predetermined threshold; and
responsive to (i) the first user device being within the predetermined proximity to the second user device and (ii) the authorization fingerprint matching the second device fingerprint beyond the predetermined threshold, authorize the login request from the second user device that has not previously been used to access the account.
