Reset the Password

From the Configuration Assistant home page, click the OPA or Service site for which you want to reset the System Administrator password.
Click the menu icon and select Reset Admin Password.
Click Yes to confirm the password reset. If successful, a message appears that the System Administrator password has been reset, and that an email containing the new password has been sent to your email address.
