A Digital Trends blogger reported he was able to use his genitals in place of a fingerprint for the Touch ID system, which can be used on the iPhone 5S to unlock the phone and authorize purchases through iTunes.
"And not only did I successfully register this private part with relative ease, I was also able to use it to unlock the device. I think you can understand why there isn't a video of this one," the blogger wrote.
The blogger said he was inspired by other bloggers' failed attempts to register body parts including elbows and nipples for the Touch ID.
Another blog, TechCrunch, recently released a video showing how a cat's paw was successfully used for the Touch ID.
