If you don't have an ssh key already and you are using Linux or Mac, you can following the steps below:
Open up the terminal. Then type:
ssh-keygen -t ecdsa -b 521 -C <your email address>
You'll want to respond in the following way:
Enter file in which to save key
Just press enter here. The default is fine.
Passphrase and Confirm
If you want to protect your key with a password, you can do so here. I recommend it since the key file is essentially your ticket into Silverback.
Then once that is completed, do:
cat ~/.ssh/id_ecdsa.pub
And send the output to the administrator. This will allow you to log into the machines you need without a password. We do it this way because it prevents brute force attempts by malicious hackers and guarantees you have a secure connection to the server. It also allows me to add you to other machines if you need access to them without any work on your part.
