I set up one server with ssh keys. I could ssh into it with the keys but my colleague couldn’t so (somehow) I managed to create a login so that he could access it without providing the keys.
Now I need to create another brand new server with similar access but whatever I do the new server requires the key. Has something changed in the setup? The old server is still accessible with just the root password but the new one says “Permission denied (publickey).”
How can I give my colleague access with just root password?

Thanks but this is just an experimental server. Convenience is more important. In any case I can reset the root password or just blow away the server.
In any case, I found the solution. When setting up the server on Digital Ocean. The form for selecting the keys is quite misleading and cost me a couple of hours.
use a user that doesn’t have a private key in their .ssh folder, because it’s trying to use your key since it found one in the default place. i would advise you disable password authentication though, and get your friend to make his own key pair and give you the public copy to put in his users home folder. allowing password logins is inferior to always using asymetric ciphers like keypairs are.
