Passing Token from iphone / ios to a website

I want to create and pass a authentication / identity token on iphone/ios and send that token to a website. The website can take this token and use this token to authenticate 开发者_StackOverflowa user/login. I dont know how to do this on ios, I was hoping anyone can help me on this. Any ideas ?

My approach in the past has been to use the ASIHTTPRequest library to send a request to your server with the login details.

This question addresses various security concerns with ASIHTTPRequest.
