Storing Credentials Securely
abyssknight: Use OAuth. http://oauth.net/That's what I'm using on FragTweet.com. To be clear, the service has to let you use it, but its still better than storing passwords. You get an authorization token from the target service that lets you authenticate as that user for certain actions which you can then store. At any time the user can deactivate the token through the service's control panel. Very slick, although not quite finished.
