Google starts rolling out Android Theft protection features

So the remote screen lock only takes a phone number? No sign in necessary??? Edit: It needs a "security challange", so better than nothing. The funnier part is you need a phone to call their number after visiting the website. At least with "Find my" I can just login anywhere and lock it.

Could I enter my friend's phone number? Could someone make a script to to lock phones at random times???

That would be infuriating.
