You can specify a different location, and an optional password (passphrase) to access the private key file. With the addition of bash aliases for the hosts, I can even quickly run commands against multiple hosts. Key-based authentication is a huge improvement over a simple username and password combination. Using the QR code. The following example uses RSA key pair, this will allow you to run scripts and login from a remote machine against RouterOS using Public/Private key authentication. Fortunately for us, SSH allows connections to be authenticated using keys. Enter the appropriate information for each of the fields. Optionally, enter a password to protect the key.

Enter a name that you will recognise as being your 2FA method for SSH, then type the secret key provided by google-authenticator command. When using this Secret type, you will have to specify a ssh-privatekey key-value pair in the data (or stringData) field as the SSH credential to use. There are two ways to login onto a remote system over SSH – using password authentication or public key authentication (passwordless SSH login). SSH keys consists of a public/private key pair. One is your public key, and the other is your private key.
