Abstract
A method of providing variably expiring passwords can include determining a complexity level for a password. Based upon the determined complexity level, an expiration duration can be calculated for the password. The password can be deactivated at a time determined by the expiration duration.
Claims23
A method of providing variably expiring passwords comprising the steps of:
- determining a complexity level for a password;
- based upon said complexity level, calculating an expiration duration for said password;
- and,
- deactivating said password at a time determined by said expiration duration.
A system for establishing password duration comprising:
- a password complexity analyzer for determining a complexity level associated with at least one password for a system;
- a password expiration means for invaliding said password after a determined duration, said determined duration being based at least in part upon said complexity level of said password;
- and,
- an administrative interface configured to allow an administrator of said system to adjust parameters controlling aspects of said system.
A machine-readable storage having stored thereon, a computer program having a plurality of code sections, said code sections executable by a machine for causing the machine to perform the steps of:
- determining a complexity level for a password;
- based upon said complexity level, calculating an expiration duration for said password;
- and,
- deactivating said password at a time determined by said expiration duration.
