Configuring Username and Password Security
Configuring Local Password Security
To Remove Password Protection. Removing password protection means
to eliminate password security. This command prompts you to verify that you
want to remove one or both passwords, then clears the indicated password(s).
(This command also clears the username associated with a password you are
removing.) For example, to remove the Operator password (and username, if
assigned) from the switch, you would do the following:
Figure 2-3. Removing a Password and Associated Username from the Switch
The effect of executing the command in figure 2-3 is to remove password
protection from the Operator level. (This means that anyone who can access
the switch console can gain Operator access without having to enter a user-
name or password.)
If you want to remove both operator and manager password protection, use
the no password all command.

The limit on username and password length is 64 characters for the following
authentication methods:
■ Front-end—WEB User Interface, SSH, and Telnet
