Patent 10320848 was granted and assigned to Microsoft on June, 2019 by the United States Patent and Trademark Office.
Embodiments are directed to having multiple lockout counters that apply to login requests from different origins. More specifically, one counter is associated with a user's familiar locations, another counter is associated with unfamiliar locations. In another embodiment, hashes of incorrect passwords are recorded so that lockout counters are not incremented multiple times when the same incorrect password is entered repeatedly.
