Facebook, Google, Twitter, Steam, etc. All of these services use two-factor authentication, or two-factor security, or 2FA, to protect their users’ accounts, which is how it’s enabled.
Double authentication —or 2FA— has become the technique with the best simplicity/efficiency ratio to secure your Google, Facebook, Twitter or other accounts.
Add, in addition to the password, a new authentication step, such as a message with a code, the use of a security key or an authenticator application. If someone tries to access your account after hacking your password, they should normally be blocked by confirming your identity, which will take place on your smartphone.
More and more services are using 2FA security to add an important layer of security. To secure an account we can distinguish three types of elements: what we know (a password), what we are (a biometric sensor such as a fingerprint or facial recognition) and what you carry (your smartphone, connected watch, etc.). Therefore, double authentication adds this last identification method to the first or second.
Here’s how to activate it on your different accounts:
Turn on two-factor authentication for a Google account
Activating double authentication in your Google account allows you to protect Gmail, YouTube or Drive. To do this, you have to find the “two-step validation” option. Go to the Google account management page, myaccount.google.com, sign in and go to the “Security” tab. There you will see the famous two-step verification option.
Follow the instructions and choose between receiving an invitation on the smartphone linked to the Google account (click “Yes” on your smartphone when it asks if the connection attempt is yours), receiving a code by SMS or by call or finally use a Security key such as the Titan key created by Google.
Enable two-factor authentication on Facebook
For Facebook, it’s just as simple. Just look for the “Use two-factor authentication” option by going to Settings, then the Security tab.
From there, you have two solutions at your disposal: go through an authenticator application such as Google Authenticator or Duo Mobile, or receive a code by SMS.
If you choose the ID app, simply download it to your smartphone, open it, and scan the QR code displayed by Facebook to link the account.
