How do you secure user EXEC mode access on the console port?

Enter line console 0, set password <pw>, then login — the login command is what actually enforces the prompt.

Switch(config)# line console 0
Switch(config-line)# password cisco
Switch(config-line)# login
Switch(config-line)# end

Steps:

1. Enter line console configuration mode with line console 0
2. Set the password with password <password>
3. Enable password checking with login

The login command is required to enforce the password requirement.
