TRON founder Justin Sun took to Twitter to make a non-SMS two-factor authentication security recommendation after the high profile account hacking of Jack Dorsey.
Jack Dorsey’s Twitter Account Hacked
Dorsey, who co-founded Twitter and created the bitcoin payment app Square, had his account hacked on Aug. 30. Despite being one of the most high-profile figures in social media, the hacker was able to gain control of Dorsey’s personal Twitter profile, publishing a series of profane tweets that were eventually deleted.
Twitter published an update later in the day, stating that Dorsey had suffered a compromise to his mobile provider, which allowed the unauthorized user to publish tweets via text messages.
The phone number associated with the account was compromised due to a security oversight by the mobile provider. This allowed an unauthorized person to compose and send tweets via text message from the phone number. That issue is now resolved.

Following on the high-profile hack, Justin Sun recommended TRON users to avoid using SMS-based security systems and instead adopt a two-factor authentication protocol like the one provided by Google.

Other community members joined Sun in his recommendation, pointing out how easy it is for hackers to enact SIM card swaps which allow for manipulation of SMS-based security systems.
While blockchains provide a secure protocol for transactions, crypto users have been at the mercy of hacks due to inadequate account and wallet protections. 2FA protocols have become a mainstay in the industry, as they require an additional layer of security beyond sending a text message.
