Two-factor authentication can make your online accounts practically impossible to hack.
November 24, 2017 - Having a strong, unique password might not be enough if hackers trick you into giving it away or steal it from your email provider or bank.
That’s why for your most sensitive accounts - think your email or banking accounts - you should set up two-factor authentication (2FA). This simply means adding a second step to log into your accounts. First, the password. Second: either a code sent to your cell phone via text message, or created by a special app on your phone. Even better, the second step can be inserting a physical token such as a security key.
