The DevicePasswordHistory element is an optional child element of type unsignedInt ([XMLSCHEMA2/2] section 3.3.22) of the EASProvisionDoc element (section 2.2.2.28) that specifies the minimum number of previously used passwords stored to prevent reuse by the client.

The DevicePasswordHistory element cannot have child elements.

If DevicePasswordHistory is not included in a response, then a client SHOULD treat this value as 0.

If the value of the DevicePasswordHistory element is greater than 0, and the value of the DevicePasswordEnabled element (section 2.2.2.25) is set to TRUE (1), the client disallows the user from using a stored prior password after a password expires.

If the DevicePasswordHistory element is included in a response, and the value of the DevicePasswordEnabled element is set to FALSE (0), the client SHOULD ignore this element.
