Description

This command sets the password for the enable mode. It can also be used to establish passwords for other levels. In the router’s configuration, the password is stored in the clear and can be viewed by using show running-config and other commands.

You can encrypt this password as well as other passwords with the command service password-encryption. However, because this encryption uses a very simple XOR algorithm, it is easily cracked.
