![]() I wanted a better solution than relying on one device. When I initially set up my Google 2FA for cryptocurrency exchanges, email accounts, and apps it was nice to know that I wasn’t susceptible to SMS based attacks but what if my phone was lost or stolen? Going through the process of contacting exchanges and companies to get a 2FA reset is a laborious process and can take 1–2 weeks to complete. Google Authenticator is not without its inconveniences though. Using an app based 2FA should always be used over SMS based 2FA. Having worked for a large telecommunications company myself, it’s unbelievable how easy it is to port a number from one carrier to the other. ![]() SMS 2 Factor Authentication is incredibly insecure, leading to the loss of millions of dollars of cryptocurrencies over the years.
