In this episode, we're diving into the process of enabling two factor authentication (2FA) for our app. We start with displaying the QR code and then move on to building out the form where users can scan the code with their authenticator app and enter the generated security code.
We'll walk through setting up the correct routes for submitting the code, catching and displaying form errors, and making sure the flow works—errors and all! You'll see the usual hiccups as we debug issues like form submissions not working due to missing handlers, and some quirks with how error messages get returned and displayed.
Once the form is hooked up, we test entering both invalid and valid codes, confirming that everything is set up properly with our backend Fortify package. You'll also see us sort out minor client-side bugs and make sure we're redirecting the user to the security/account page after they've successfully enabled 2FA.
We go through the entire enablement flow a couple of times to make sure it works from start to finish. By the end, our user can enable two factor authentication, and the UI updates to reflect this state. Next, we'll look at how to toggle 2FA off again and eventually prompt users for their code when they log in. A little troubleshooting, but now we've got 2FA up and running!
