Yes, it is possible using xauth

You need to get approval to use xauth:

xAuth access is restricted to approved applications. If your application is a desktop or mobile application and the standard web OAuth flow or PIN-code out-of-band flow is not right for you, send a detailed message to api@twitter.com to request xAuth privileges.
