You can continue to press the Up arrow key for more commands. The

Enable Secret and Enable Passwords
Because many privileged EXEC commands are used to set operating parameters,
you should password-protect these commands to prevent unauthorized use.
You use two commands to do this:
• enable secret password (a very secure, encrypted password)
• enable password (a less secure, unencrypted password)
You must enter an enable secret password to gain access to privileged EXEC mode
commands.
