Seems like Apple is planning to implement multi-user mode in iOS with face recognition based login ie a user just enter his PIN, however, the camera detects which account to load. (IMHO, more secure than the current Android implementation) Article talking about related patent: http://www.cultofmac.com/137393/apple-patent-details-facial-recognition-plans-for-macs-ios-devices/ http://www.cultofmac.com/137393/apple-patent-details-facial-... I would imagine at that time, they might support Guest logins. EDIT: the implementation detail of Face recognition talked above is my own take on how it should be done. Not suggested by the referenced article.
