Understanding Enable and Enable Secret Passwords
Some privileged EXEC commands are used for actions that impact the system, and it is recommended
that you set a password for these commands to prevent unauthorized use. Two types of passwords, enable
(not encrypted) and enable secret (encrypted), can be set. The following commands set these passwords
and are issued in global configuration mode:
• enable password
• enable secret password
