I think I see what the OP meant, here are relevant excerpts from the article. New API access:

> Beginning today, anyone who wants access to Twitter’s APIs should apply for a developer account using the new developer portal at developer.twitter.com.

Existing API keyholders:

> Eventually, all developers with existing access to our APIs will be required to complete a developer account application in order to maintain their apps.

Maybe i'm misreading it, but it looks like you're essentially just filling out a form with your contact info and agreeing to the T&C for the initial "application".
