Eight years have passed since Google implemented two-factor authentication (2FA),owa two factor authentication but almost no one uses it so far. In 2018, Software Engineer of the company Grzegorz Milka made a presentation at Usenix’s Enigma IT Conference. He showed sad numbers of how ordinary users care about their security: approximately 10% of active Google clients use 2FA and only about 12% use password managers. Surprised? Probably, it is time to think about the usage of 2FA.
