After logging in to a service, go to security and privacy settings. There you will find the Two-Factor Authentication option. After activating it, you will see a QR code and a private key. Open your 2FAS app and add this service by scanning the QR code or copying the private key. The last step of activating 2FA in the service is to rewrite the code from the 2FA app. Remember that now every time you log into the website, you will have to enter your login and password and then rewrite the 2FA code generated by the app – so do not remove the code or uninstall the 2FAS application from your phone!
We’ve created multiple tutorials on how to set up 2FA for various online services on our website https://2fas.com/how-to-enable-2fa/. If you don’t find a particular service there, try typing its name + ‘2fa’ on Google or Youtube.
