[twitter-dev] TweetDeck does no redirect to Twitter Authenticating page and uses OAuth ?

[Json West]

Hi Folks,

I know that after version 0.33 TweetDeck is using OAuth, all twitter
clients had to do that since June.
But when I've signed up a new Twitter Account on TweetDeck, I was not
redirected to any Authenticating Twitter website. So , how OAuth is
working on TweetDeck ?

thanks
