How can I add a new SSH to my server?

Question

I’m new to this, when I created my DigitalOcean “project” it allowed me to enter an SSH key, it works great!

Now I want to add an SSH key for another computer, but I don’t see an option anywhere for that :(

You can follow out tutorial in order to generate a new ssh-key locally on your computer or any other PC and then upload it to your droplet:

ssh-keygen -t rsa

Once this is done you can simply copy the idrsa.pub key file to the authorizedkeys file on your droplet using this command:

cat ~/.ssh/id_rsa.pub | ssh demo@IPaddress "mkdir -p ~/.ssh && chmod 700 ~/.ssh && cat >>  ~/.ssh/authorized_keys"

Hope this helps!

Alex
