I am trying to create a passwordless login with SSH and I think I activated the wrong public key as the authentication key. I tried to add the other key to the authenticated_keys file but my permission is denied, I tried to delete and redo the process but again my permission is denied, then I tried with the ssh-copy-id as on the link attached and this also was denied. I have tried to change permissions with "chmod" but nothing works. What can I do now? I am new to SSH but I use rsync already to exchange data between devices but with a password login which I want to remove.
