During the rain delay at the PGA Championship, Rory McIlroy was checking his iPhone. Unfortunately, the cameras were rolling when he was unlocking it, revealing his pass code to everyone who was watching.
As you can see in the above Vine, the code was 4589, or McIlroy's birthday, which is May 4, 1989.
McIlroy made sure to mention that he changed his pass code over Twitter:
Once play resumed, the 25-year-old from Northern Ireland found himself in a dogfight. He carded a three-under 68, holding off Phil Mickelson, Henrik Stenson, Rickie Fowler, Jim Furyk and a host of other challengers to claim his fourth major.
