I'm using an old login with ssh-rsa public/private key and all was good.
I noticed that a couple of days ago the authorizazion was avoid with message "server refused our keys". After diggin' I figured out that the couple of keys stop working after exactly 5 years of their creation.
So I make a new pair of keys, take the public one, paste inside a file in ~/.ssh of the username that I'm using, converted it with ssh-keygen -if and paste the new file into authorized_keys but the I still get "server refused our key".

It's ok to copy and paste the real key without transfer it?

What I'm missing? This isn't my first time using a pair of keys and I follow the same procedure as described. I'm in doubt if I'm changing the correct authorized_keys file but I've take a look in /etc/passwd and see where is the home of the login which I'm using.

I did it out of a sense of security, just like different passwords to different sites. Does having multiple SSH keys actually improve security? All of them are used from the same machine… >>> More
