WATCH: Is this the longest iPhone passcode ever?
This man has better memory than most people.
One sneaky commuter caught this whopper passcode on camera while travelling on a train in Japan.
The man quickly rambles off his lengthy passcode without a second though.
Without even knowing it, the man has started an internet code cracking competition, to see if anyone can decipher what was typed into the phone.
Close to 200,000 people have since watched the video, which has been broadly shared over the weekend. Many of those are now taking to forums to publish what they say is the passcode.
One user says it racks up an impressive 59 characters which are: : "197712311199925255 2622115104104 1881041911073923021501231287365."
