Are you excited for mid-April 2019? If you’re not, you’re either working over the holiday weekend or you’re not a Game of Thrones fan. The immensely-popular series is coming to an end but every conclusion needs a beginning. The first official trailer for Game of Thrones Season 8? That qualifies.

Despite what every spy movie in the past 30 years would have you think, fingerprint and face scanners used to unlock your smartphone or other devices aren’t nearly as secure as they’re made out to be.
