This document describes the procedure for recovering an enable password or replacing enable-secret passwords on Cisco 801, 802, 803, 804, 805, 811, and 813 Series Routers. These passwords are used to protect access to privileged EXEC and configuration modes. The enable password can be recovered because it is displayed in plain text in the configutaion file.
