README

This bundle is in the alpha stage and is not recommended for production use.

This repository is forked from Novactive/NovaeZ2FABundle and upgraded to work with Ibexa 4.x

Netgen Ibexa 2FA Bundle provides two-factor authentication for your ibexa project.

Installation

Requirements

Ibexa 4.x
PHP 8.1

Use Composer

Add the lib to your composer.json, run composer require netgen/ibexa2fabundle to refresh dependencies.

Register the bundle

Then inject the bundle in the config\bundles.php of your application.

    return [
        // ...
        Scheb\TwoFactorBundle\SchebTwoFactorBundle::class => ['all' => true],
        Netgen\Bundle\Ibexa2FABundle\NetgenIbexa2FABundle::class => [ 'all'=> true ],
    ];

Add routes

Make sure you add this route to your routing:

# config/app/routes.yaml

_netgen_ibexa2fa_routes:
    resource: '@NetgenIbexa2FABundle/Resources/config/routing.yaml'

    email:
        enabled: true                            # If email authentication should be enabled, default false
        mailer: Netgen\Bundle\Ibexa2FABundle\Core\AuthCodeMailer # Use alternative service to send the authentication code

        sender_email: me@example.com             # Sender email address
        sender_name: John Doe                    # Sender name
        digits: 6                                # Number of digits in authentication code
        template: "@ibexadesign/2fa/auth.html.twig" # Template used to render the authentication form

    # The security token classes, which trigger two-factor authentication.
    # By default the bundle only reacts to Symfony's username+password authentication. If you want to enable
    # two-factor authentication for other authentication methods, add their security token classes.
    # See the configuration reference at https://github.com/scheb/two-factor-bundle/blob/4.x/Resources/doc/configuration.md
    security_tokens:
        - Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken
        # If you're using guard-based authentication, you have to use this one:
        # - Symfony\Component\Security\Guard\Token\PostAuthenticationGuardToken
        # If you're using authenticator-based security (introduced in Symfony 5.1), you have to use this one:
        # - Symfony\Component\Security\Http\Authenticator\Token\PostAuthenticationToken

# Whether to use the backup codes or not should be specified here in parameters section, then used in scheb_two_factor.backup_codes
# It's done this way in order to let the user customize if the backup codes should be generated or not
parameters:
    nova_ez2fa.backup_codes.enabled: true

If email method is enabled then MAILER_DSN env variable should be specified in the .env file

Note to keep in mind: This bundle is Siteaccess aware so each Siteaccess can have different authentication method.

# config/packages/nova_ez2fa.yaml

netgen_ibexa2fa:
    system:
        # Available mobile methods - google, totp, microsoft or null.
        # If microsoft is selected the totp mechanism is still used but the config is forced and static so Microsoft Authenticator app can be used.
        # Email method can also be enabled or disabled for each siteaccess
        # If 2fa_force_setup is true then the User must always set up 2FA upon authentication and reset function is off
        default:
            2fa_mobile_method: google
            2fa_email_method_enabled: true
            2fa_force_setup: false
        site:
            2fa_mobile_method: totp
            # if microsoft method set - the config is forced to: algorithm: sha1, period: 30, digits: 6
            config:
                algorithm: sha1 #(md5, sha1, sha256, sha512)
                period: 30
                digits: 6
            2fa_email_method_enabled: true
            2fa_force_setup: false
parameters:
    netgen_ibexa2fa.backup_codes.enabled: true

Create the table in DB:

See the file bundle/Resources/sql/schema.sql

Especial instructions for HTTP Cache

Important!: For the HTTP Cache system (e.g. Varnish or Fastly) the following logic should be implemented:

if (req.url ~ "^/2fa") {
    return (pass);
}

and it should be added before the call ez_user_context_hash line.

We need it in order to avoid triggering the X User Hash mechanism when /2fa request is sent, so the /_fos_user_context_hash request would not return 302 redirect response because of this bundle.

Manually removing 2FA record for specific User:

If some User needs its 2FA record in the database removed to be able to login without entering 2FA code run the following command acx:users:remove-2fa with specifying user's login:

php ezplatform/bin/console nova:2fa:remove-secret-key user_login

Note to keep in mind: If you have the 2FA already set up for the user and you're going to reset it by following the corresponding link on the 2FA Setup page don't change the method for the current Siteaccess before that! Because in this case the secret key will be supposed to be removed for the new method not for the old one and hence the reset won't work!
