Two-factor authentication, also known as multi-factor authentication, is one of the best ways to protect your precious data from hacking and other malicious online activity.
If you are using email, online banking, social media, or at just about anything on the internet that requires logging in, two-factor authentication is the best way to protect yourself and your data.
After you set up TFA, you are temporarily blocked from logging in from a new device. So if someone tries to login on an unrecognized device, you will receive a notification on your device via text message or through a separate app which you have previously installed.
Some people find it annoying, but it is much more annoying to lose all of your money and /or your data!
