What is SSH authentication?
SSH provides authentication and encryption functions that enable you to configure your system to meet your security requirements. By default, SSH is configured for username and password authentication, but you can add public key authentication and additional multi-factor authentication (MFA) provided through other modules (like OATH-TOTP). Multi-factor authentication proves more resilient against phishing attacks than a password alone because MFA requires at least one other factor beyond a password to confirm an identity.

Objective
The objective of this lab is to configure the switch for remote management such that the laptop PC residing on a remote network be used to login and manage it via ssh . To accomplish this, the following will be done:
Implementation
The following configuration commands will the required to configure a Cisco switch for remote management. The commands used here a for the lab represented in the network topology used here. However, the solution can be achieved in many different ways.
Verification
To verify that I have configured the Cisco switch for remote management via ssh, I try to access the switch using the laptop on the network 192.168.0.0/24 using ssh. Remember that both the laptop and the switch are on different networks. See the result below.
