Tokens is an OAuth term. Oz uses encapsulated “tokens” – called tickets. You can see how they are created and parsed in tickets.js.
Bearer tokens are an OAuth concept that is not supported in Oz. Also, MAC tokens never really made it out of the OAuth working group. I did create a replacement for those looking for OAuth 1.0 style authentication (2-legged) called Hawk this weekend:
