  • Preventing malicious lockout of user accounts
    Patent number: 11042629
    Abstract: An authentication server in an illustrative embodiment is configured to communicate with one or more client devices over a network. Responsive to a successful login to a user account by a client device, the authentication server provides the client device with a login cookie for the user account for potential utilization in one or more subsequent logins to the user account. The authentication server initializes a cookie-specific counter for the login cookie, and increments the cookie-specific counter for each of one or more unsuccessful logins to the user account made utilizing the login cookie. Responsive to the cookie-specific counter reaching a specified value, the authentication server locks the user account for any subsequent logins to the user account made utilizing the login cookie. The authentication server resets the cookie-specific counter responsive to a successful login to the user account made utilizing the login cookie.
