To carry out a remote login without the authentication, with the pair user and password, is to install on the remote machine the public part of our authentication key.

The problem is that, for having an automatic login, the authentication key must not be protected with a password.
This method is quite safe, assuming that the private part of our athentication key doesn't fall in to the wrong hands!
