You can login with password or with certificates. To generate certificates use this commands and accept all questions with enter:

ssh-keygen -t rsa
ssh-keygen -t dsa

This will generate a public and private certificate pair under ~/.ssh/ 

Now you can authorise a user with the gernated public certificates on other machines. You only need to copy the content from the public certificates to the other remote systems in this file~/.ssh/authorized_keys

For this purpose there is a special ssh tool:

ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
ssh-copy-id -i ~/.ssh/id_dsa.pub [email protected]

Without that tool you can do it this way:

cat ~/.ssh/*.pub | ssh [email protected] 'umask 077; cat >>.ssh/authorized_keys'
