For an assignment I have to make the CMS-system easily accessible trough mobile devices. Ideally we would like to create a way for user authentication with the least amount of input possible.
I have created a system with php/javascript which mimics the android pattern lock, so at this moment a user can login by swiping a pattern. But the problem remains that they still have to manually type a username.
Would it be possible to get some sort of unique ID from a smartphone, so we can store this in the database and link it to an account. So that if a user wants to login in to the CMS, he only has to browse the website, the system will recognize who he is, he swipes his pattern and the user is authenticated!
