From e8d41bc2fe9418613cdc118c8674fc5fe7856685 Mon Sep 17 00:00:00 2001 From: santiagorodriguez96 <46354312+santiagorodriguez96@users.noreply.github.com> Date: Mon, 24 Aug 2020 11:46:27 -0300 Subject: Add WebAuthn as an alternative 2FA method (#14466) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: add possibility of adding WebAuthn security keys to use as 2FA This adds a basic UI for enabling WebAuthn 2FA. We did a little refactor to the Settings page for editing the 2FA methods – now it will list the methods that are available to the user (TOTP and WebAuthn) and from there they'll be able to add or remove any of them. Also, it's worth mentioning that for enabling WebAuthn it's required to have TOTP enabled, so the first time that you go to the 2FA Settings page, you'll be asked to set it up. This work was inspired by the one donde by Github in their platform, and despite it could be approached in different ways, we decided to go with this one given that we feel that this gives a great UX. Co-authored-by: Facundo Padula * feat: add request for WebAuthn as second factor at login if enabled This commits adds the feature for using WebAuthn as a second factor for login when enabled. If users have WebAuthn enabled, now a page requesting for the use of a WebAuthn credential for log in will appear, although a link redirecting to the old page for logging in using a two-factor code will also be present.

Instead, users will have to click on 'Disable 2FA' in order to remove second factor auth. The reason for WebAuthn being secondary to TOPT is that in that way, users will still be able to log in using their code from their phone's application if they don't have their security keys with them – or maybe even lost them. * We had to change a little the flow for setting up TOTP, given that now it's possible to setting up again if you already had TOTP, in order to let users modify their authenticator app – given that now it's not possible for them to disable TOTP and set it up again with another authenticator app. So, basically, now instead of storing the new `otp_secret` in the user, we store it in the session until the process of set up is finished. This was because, as it was before, when users clicked on 'Edit' in the new two-factor methods lists page, but then went back without finishing the flow, their `otp_secret` had been changed therefore invalidating their previous authenticator app, making them unable to log in again using TOTP. Co-authored-by: Facundo Padula * refactor: fix eslint errors The PR build was failing given that linting returning some errors. This commit attempts to fix them. * refactor: normalize i18n translations The build was failing given that i18n translations files were not normalized. This commits fixes that. * refactor: avoid having the webauthn gem locked to a specific version * refactor: use symbols for routes without '/' * refactor: avoid sending webauthn disabled email when 2FA is disabled When an admins disable 2FA for users, we were sending two mails to them, one notifying that 2FA was disabled and the other to notify that WebAuthn was disabled. As the second one is redundant since the first email includes it, we can remove it and send just one email to users. * refactor: avoid creating new env variable for webauthn_origin config * refactor: improve flash error messages for webauthn pages Co-authored-by: Facundo Padula --- .../webauthn_credentials_controller_spec.rb | 374 +++++++++++++++++++++ 1 file changed, 374 insertions(+) create mode 100644 spec/controllers/settings/two_factor_authentication/webauthn_credentials_controller_spec.rb (limited to 'spec/controllers/settings/two_factor_authentication/webauthn_credentials_controller_spec.rb') diff --git a/spec/controllers/settings/two_factor_authentication/webauthn_credentials_controller_spec.rb b/spec/controllers/settings/two_factor_authentication/webauthn_credentials_controller_spec.rb new file mode 100644 index 000000000..fe53b4dfc --- /dev/null +++ b/spec/controllers/settings/two_factor_authentication/webauthn_credentials_controller_spec.rb @@ -0,0 +1,374 @@ +# frozen_string_literal: true + +require 'rails_helper' +require 'webauthn/fake_client' + +describe Settings::TwoFactorAuthentication::WebauthnCredentialsController do + render_views + + let(:user) { Fabricate(:user) } + let(:domain) { "#{Rails.configuration.x.use_https ?
