How to pass authentication in Flickr without opening a browser?

I'm developing Flickr client. It's a desktop application.

I need to pass authentication without opening a browser i.e. I have 2 fields for login and password and when user press "Log in" 开发者_运维百科button all authentication steps should be performed behind the scenes.

Flickr API actually offers to open a default browser and let user pass authentication manually.

What is the way of this situation?

Here's what I think is a similar question on the FlickrNET API Discussion board:
