SpaceX CEO Elon Musk practices a rather drastic measure when it comes to mobile security: the trashcan.

In a new legal document reads that the multi-billionaire tech mogul Elon Musk regularly switches to new smartphones and destroys old ones for security purposes.lon Musk regularly switches to new smartphones and destroys old ones for security purposes.

“For security purposes, Musk regularly changes his cellular device, at which time his old device is imaged, wiped clean, and stored or destroyed,” The Business Insider reported on Friday citing the October 14 document.

The documents were submitted as part of an ongoing court case between Musk and a diver named Vernon Unsworth who sued the CEO for defamation after he called Unsworth ‘pedo guy’ on Twitter last year.

The exchange came after Musk suggested using a mini-submarine to help save a youth soccer team and their coach who were trapped inside a cave in Thailand that Unsworth described as a publicity stunt.

Musk has since apologized for the comments adding recently that he only made them because he is a ‘f*****g idiot.

“Musk updates his phone (like lots of other people) and he occasionally has to change his phone for reasons that have to do with security and sensitive information,” Alex Spiro, an attorney for Musk, told Business Insider.
