Embodiments of a computer system, a method, and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to evaluate a user request to regain control of an online account. For example, the user request may be submitted online using a web page, and may include information that establishes the user's identity or that substantiates that the user is the owner of the online account, such as a history of recent activities associated with the online account. This information may be evaluated by comparing it to stored information associated with the online account, such as a stored history of recent activities or one or more locations of a registered user when the registered user previously accessed the online account. After evaluating the user request, remedial action may be performed.
