iOS authentification, security and single sign-on?

[sparetire]

Is there a way to handle single sign-on?

Since the device itself is secured, it would be nice if I can automatically log the user into my website (through an app which sends over an identifier for the device, eg. serial number or even phone number, and some sort of security token).

You can use the Unique Identifier.
