How to set SSH key for multiple users?

I currently have 3 accounts on my droplet, for this case I’ll be using the names “root”, “a”, and “b”. I have my SSH key set up so that it currently applies to account a. How do I apply it to the root account as well, but not to account b?

Greetings!

Great question. There are several ways to do this, but this is mine:

  1. Switch to the user:
su a
  1. Generate SSH keys:
ssh-keygen
{hit enter a few times}
  1. Create/edit authorized keys file:
nano ~/.ssh/authorized_keys

  1. Paste your public key in that file and close it out.

  2. Rinse and repeat with each user.

Everyone has preferences, that one just fits my brain :)
