Sure. Use ssh-keygen to generate your public/private key but don't
put a passphrase on 'em. Then put the contents of identity.pub into
~/.ssh/authorized_keys on every system you want to login to.

machineA> ssh-keygen
machineA> scp ~/.ssh/identity.pub machineB:.ssh/machineA.pub
machineA> ssh machineB  # Password required
machineB> cat .ssh/machineA.pub >> .ssh/authorized_keys
machineB> chmod 700 .ssh
machineB> chmod 644 .ssh/authorized_keys
machineB> chmod 644 .ssh/*.pub
machineB> logout
machineA> ssh machineB  # Password not required

This should work if you're using OpenSSH and if I haven't
forgotten something. The ssh-keygen manpage should get you
through.
