From configuration mode, we have direct access to the console, selecting line 0.
We need to choose the password and login command, to ensure that password will be required during new console access.
This new created console password is universal for all users connecting to switch.

We can check the console settings from configuration file on the switch.
The line circled with red, shown that console requires the password to login.
Blue circle area displays virtual lines which are part of telnet or SSH protocols.
Picture 4 - Secret password from privilege mode
The next option that improves security on a switch or router is the password option in privilege mode.
This password is similar like console one, set up for all users which login to switch or router.
This password of privilege mode must be setup when we remotely login to the device.
There are two options: secret and password. The secret command creates encrypted password.
