Is two-factor authentication (2FA) as secure as it seems? | Advanced Mobile Spy Software
Two-factor authentication (2FA) was invented to add an extra layer of security to the—now considered old-fashioned and insecure—simple login procedure of entering a username and password. One of the most well-known examples of 2FA is when you try to log into a familiar website from a different machine or from a different location, which results in a different IP. With 2FA-enabled login procedures, you will first enter your username and password on the computer and then receive a text message to your phone providing you with a verification code.
