US Patent 10404683 Strength-based password expiration

A password application system receives a credential for a first privilege of a plurality of privileges whereby the first privilege corresponds to a first set of credential requirements and the plurality of privileges have a second privilege that corresponds to a different set of credential requirements. The system determines whether the credential for the first privilege satisfies the first set of credential requirements. If the credential satisfies this set of credential requirements, the system enables the credential to be used for access in accordance with the first privilege.
