To create keypairs for SSH logins using public key authentification it
is absolutely BAD and highly NOT RECOMMENDED to create keys WITHOUT a
passphrase! Once the private key is stolen it can be used without
problems. While it is secured by a valuable passphrase it is useless
unless the thief can brute force crack the passphrase (which implies
that the passphrase was badly choosen, too simple).

To get an authentification process using SSH which requires not the
input of a passphrase or password (just for the first time) there are
the tools ssh-agent and ssh-add. Dave explained that already in his
reply.

NEVER create keypairs without a passphrase or create an account without
password protection!
