Now this sounds like a great WOWODC talk, especially by someone that has just implemented it!

I'd definitely be interested to see what others have done with it. I'm actually really looking forward to getting it done. It should definitely simplify a lot of the "log in" process as far as my app is concerned.

One is the CardDAV notion and second is this "assertion authentication" pattern that has been implemented by Mobile Access Service, OpenSSO, and Shibboleth. A link to the CardDAV reference, even if kept semi-private, would be sufficient to have a unique reference to any user to be had. Since both Apple and Amazon seem to be making such a standard available, then it makes sense for authorization.

Quite similar that it creates new user password, authenticates user/password and returned error messages. It also has the user capabilities on the access module level. I used "Sha-1", and I thought it should be good enough for hash algo. Is it secured enough? Otherwise, I could change to DES/3DES/ MD4/5 etc.
