You can add it to ssh-agent, and it will be kept open for new connections to use.( and, even allow you to extend the keyed login to the next hop) Some desktops will do this automatically, Some are setup to ask for the password each time.

Something I've considered doing is creating a truecrypt volume and somehow sticking all of my pre-shared keys and stored credentials in there, for SSH keys , wifi keys , lastpass & dropbox credentials etc.

So I can mount the volume and be logged automatically into everything then dismount when I'm done.

It's just the pain of rounding all of the various files up.

Or just use ssh-agent, encrypt your key, and store everything per-file encrypted in Dropbox like everyone else does.

OSX Keychain stores wifi keys encrypted on disk with a key derived from your user account password.

The only passwords I need to remember are my for my GPG key, my ssh key, Dropbox, and 1Password. Oh, and my user account.

I'd rather not use per file encryption with dropbox because that could break syncing in big files.

The idea would be to have everything auto-login when the drive is mounted and nothing auto-login when it is not.
