Just last week, Instagram confirmed reports that it’s modifying its two-factor authentication setup to allow users to log in with passcodes from security apps—like Google Authenticator. While this isn’t the sexiest of news, it’s great to see this practice growing in popularity: using a token-based app, rather than a text message, to authenticate into other apps and services.  

You should be doing this whenever possible. There are plenty of reports that have shown just how easy it is for a hacker to call up a cellular carrier, find an unsuspecting customer service agent, and pretend they’re you.
