Configuring the Enable and Enable Secret Passwords
To provide an additional layer of security, particularly for passwords that cross the network or are stored on a TFTP server, you can use either the enable password command or enable secret command. Both commands accomplish the same thing—they allow you to establish an encrypted password that users must enter to access privileged EXEC (enable) mode.
We recommend that you use the enable secret command because it uses an improved encryption algorithm. Use the enable password command only if you boot an older image of the Cisco IOS software or if you boot older boot ROMs that do not recognize the enable secret command.
For more information, see the “Configuring Passwords and Privileges” chapter in the Cisco IOS Security Configuration Guide. Also see the Cisco IOS Password Encryption Facts tech note and the Improving Security on Cisco Routers tech note.
Restrictions
If you configure the enable secret command, it takes precedence over the enable password command; the two commands cannot be in effect simultaneously.
