Is there anyway I can watch the fault in our stars on my iphone free?

I've tried some sites but they all need credit card details which I don't have. Or I'll go on a site and it'll only work on a computer which I also don't have.

Does anyone have a site that will work on my iphone, that I don't have to make an account on? Or a link to a youtube version that actually works, instead of making you go to a different site?

Should I be worried about my iPhone?

So not long ago, I had a message on my iPhone saying "you must change your pass-code within the next 60 minutes" (the 4 digit number)

So I went along with it and changed it, but I'm not sure if it a virus or malware or something. I have never seen it come up before and it has me worried. Has anyone else had this? And any help is nice, thank you.

Added (1). it was like a pop up on my home screen

Added (2). and it was the pass-code for when you lock your phone and have to enter the pass code to unlock it.
