VIDEO: You won't believe how long this guy's iPhone passcode is

What a memory!

If you’re an iPhone owner you'll know that pain of having to remember a passcode to unlock your device.

For most of us it is generally something simple, like numbers that have personal meaning i.e birthdays, anniversaries ... that kind of thing.

We'd all like to have something as easy as the classic ‘0000’ or ‘1234’, but that's not going to keep the thieves out of your phone.

While travelling on a train in Japan Twitter user @yossy1999116 filmed a man entering a crazy amount of numbers in order to unlock his phone on Saturday.

Wow! That's tight security!

The odds of anyone guessing that (without seeing the video) must be mind-boggling.

This guy must have an unbelievable memory!
