lon Musk has announced via Twitter that the Tesla app will feature a two-factor authentication for upgraded security, admittedly, a little late than expected.
Tesla App 2FA
"Sorry, this is embarrassingly late. Two factor authentication via sms or authenticator app is going through final validation right now."
Most big name apps in the online stores have a two-factor authentication, which includes the likes of Google, Facebook, and twitter, and in the near future, Tesla will join the group of heavyweights to include the security feature. Currently the Tesla app uses a single-factor authentication which only consists of an email address and password, or if available, face ID.
Tesla hasn't been entirely immune to "car hacking" as it was found it that hackers could steal a model S by cloning the key fob, although this method of theft was taken care of.
Two-factor authentication, which is also known as 2FA, is a secure method of confirming user identities by using a specific combination of two factors. Commonly these factors include a knowledge factor, which is something the user knows such as a password or PIN, and a possession factor, which is something the user has such as an ID card or mobile device used to approve authentication request. A location factor, and time factor are also used but are uncommon.
Why is 2FA Important?
Good security comes in layers, and many people use weak passwords or share multiple logins across different services whether it's Google, Facebook, or even for smaller applications and websites. So, the last thing you want happen is for a different profile to be hacked, only to lead the hacker to your brand new Tesla Model X Performance.
