The user agent flow works for native apps that can host a web browser. It works pretty well in my experience. Secrets on native apps are good! The key is (no pun intended) that the secret *not ship with the app*. Each client should register for its own client_id and secret when it is installed on the client machine. -- Andrew Arnott "I [may] not agree with what you have to say, but I'll defend to the death your right to say it." - S.
