My son's phone updated a week ago. Asks for the password, one that he didn't set up. I have gone to Verizon I have talked to Samsung. NO ONE can help. All they keep saying is factory reset.  Why is this happening after an update?!? Get it together!

You would have set up a password when setting up the phone, It is required. This is also the UK forume.

Try his email password if he is using his email for Samsung account

Or yours if you set it up for him
