"During the Self Service Password Reset installation, you specify a Configuration Password. Self Service Password Reset requires the Configuration Password prior to any modifications of its configuration. In the unlocked configuration mode, it is possible to delete the current Self Service Password Reset configuration, and then reconfigure Self Service Password Reset as if it is a new installation, including specifying a new Configuration Password."
Can I just reset the password without deleting the entire configuration? That seems a bit dramatic.
