Best WiFi password ever?

The word "fourwordsalluppercase” looks simple enough, but trying to explain it to anyone is almost impossible.

As the video produced by RocketJump shows, people’s initial instinct is to type the infuriating phrase in upper case as four separate words.

When it’s explained that it’s actually "one word, all lowercase” things get even more confusing.

The YouTube clip, which was uploaded earlier this week, has now gone viral with over 1.5million views in just two days.

So, if you want to keep the family off your Wi-Fi this week it might be worth heading to your settings and changing the password.

Then when everyone arrives for the holidays, you can sit back and enjoy the chaos as your loved ones attempt to log in.
