Abstract
Conference calls are managed using a permanent or default password associated with a particular call-in phone number and at least one temporary, dynamically-generated password for that same call-in phone number. The temporary passwords are preferably applicable for a particular time period or interval. If a temporary password is not defined for the time period in which a conference call takes place, the default password may be used. Conference call access is restricted to participants who provide the proper password—namely, the temporary password during a time period for which a temporary password has been generated, and the default password otherwise.
