Apart from ssh-agent which other's have suggested. If you don't enter a
passphrase when creating the key it won't ask for one - good for
scripting, etc.

Also if your looking for a single sign on, so Email / Web servers / SSH
servers don't ask for passwords when using - like a Windows AD
enviroment have a look at Kerberos & LDAP.
