I managed to sign in to my Cerbo GX as root by setting a pasword. After this I setup an ssh key so I can automatically log in using my certificate. In my opinion this only makes sense when I can remove the password for the root user, otherwise people still can try the password.
However, when I expire the root password I loose access altogether. (passwd -l root)
Is there a way to remove the root password and still be able to login using the set ssh key?
