I want to let my users tweet to their own account via my application. Can I do this without them needing their own Key etc?

I was hoping to allow users of my application to enter their Twitter username and password and then to allow them to tweet via my application.

E.g. So they can schedule the release of some tweets.

I have managed to tweet OK from PHP to my own account, but surely I don’t have to ask all my customers to register an “Application” and get keys and tokens etc.

What am I missing?
