rclone authentication via tty

I have been using rcolne for quite some time and I thing it is the best tool to deal with your cloud accounts and to sync the data without any bells and whistles usage. But the only problem of which I have not gotten any workaround is this that I have installed gentoo and most of my time I spend on terminal only so I haven't installed X on it. Now, for rclone be used I need authorization of my dropbox account (so that I can sync my files). But I do not think I will be able to do it via links or elinks browser. So, the question is whether there is any workaround for this so that I can get authorization done without using X or any other text based tool so that I can sync to my cloud account (other then rclone)?
