I know the answer is out there, but I\'m pretty Unix-dumb and probably wouldn\'t recognize the solution if it hit me in the face.
I\'m on a Mac, connecting to a SVN
sshkeychain is one possibility. installs fine with macports using:
sudo port install sshkeychain
it uses the keychain to store passwords, and you may simply launch it at the start-up of your login session (using at the first launch the usual right-ght click in the dock's icon + "launch at startup")
Note that Apple's svn uses keychain to store passwords but not necessarily the svn binary you would build with macports.
