I'm attempting to implement 3-legged OAuth and I saw a post from 3 years ago stating the Authorization Code expire time is 5 minutes. Has this changed since then? It seems to be much shorter as by the time I copy/paste my authorization code into my app (after about 5-10 seconds), I get an error "Authorization Code is Expired".
I'm implementing a desktop application but the authorization code request is done via a web page, so I was thinking of having the user authenticate and then copy/paste the auth code into the desktop app which then requests a token.

Please let me know if I need to change my approach due to the expire time.
Thanks!
