Overview#

Password History is a list of passwords used by a Entity

The Password Policy Administrator sets one or both of the following:

• number of passwords to be stored in the Password History at any given time.
• length of time that passwords are kept within the Password History

Passwords are stored in this Password History whenever the Password Change.

Typically, Password Policy settings may imply Users aren't allowed to specify any passwords that are in the Password History list while changing passwords.
