Hacking and bypass someone's website is the order of the day now which is why it's very important that you have a 2FA security set up on your website to prevent any intruder. I even make use of it on all of my social media sites and none of my accounts have been hacked.
Making use of two-factor authentication is very necessary for your website and even every of your social Media account because it is what will prevent hackers from having access to your account as it will prevent them login into any of your account.
It's suicide not using two-factor authentication in all your online social media accounts, forums and also financial accounts too. A lot of people have lost their accounts because they didn't enable two-factor authentication.
