Claim:
1. A method for managing access to a resource by an access manager, the method comprising: designating, at a first time, a variable attribute of a recurring public event as a shared secret between the access manager and a user, wherein the recurring public event is not associated with the resource; receiving, at a second time occurring after the first time, a shared key from the user, the shared key based on a value of the variable attribute of the recurring public event at a most recent recurrence of the recurring public event relative to the second time; evaluating the shared key; granting, in response to the evaluating, the user access to the resource; monitoring the variable attribute of the recurring public event; determining, based on the monitoring, that the variable attribute of the recurring public event fails to achieve a variability threshold; and designating, based on the determining and in place of the variable attribute of the recurring public event, a second variable attribute of a second recurring public event as the shared secret between the access manager and the user.
