Configure 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 XE
software.
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.

2. configure terminal
3. enable password password
4. enable secret password
5. end
6. enable
