Hi,
I am a new beginner and my plan is to establish secure SSH and disable root login on my Ubunto server.
I followed this video and I am able to SSH into the server:

To my big surprice I also tried from another PC and was also able to SSH into the server even if the private key was not on the other PC?? I was asked for the password and after entering it I was in.. I tought it was not possible without a private key on the other computer?
What am I missing?
Best regard, J
