Enable dual authentication on your online accounts (2FA)

Nobody is spared from piracy. In the digital age and with all personal data that we leave on the various online platforms, it is strongly advised to strengthen the security of our accounts.

Here's a simple way to enhance the security of your key online accounts: dual authentication (also known as 2FA or Two-factor authentication, or sometimes even A2F).

Double authentication helps strengthen the security of your account by adding a secondary step to the login process. The first step is the usual connection: you provide your username and password. The second step is to copy a temporary code that you will have received by SMS, or through an authentication application for your smartphone.

So if a hacker can discover your password, he will not be able to access your account without your smartphone 🙂

WordPress

For WordPress sites

If you have a WordPress site and want to protect it, I advise you to directly install a firewall like Wordfence. This extension will allow you to activate double authentication for the different accounts of your site. It will also allow you to strengthen the overall security of your site by analyzing the activities on your blog.

If you want to install a lighter extension than a firewall, you can simply install a extension that adds dual authentication

For the wordpress.com platform

  1. Log in and go to the configuration page
  2. Then click on Get Started
  3. Enter your phone number and follow the instructions
