Setup MFA Authentication Provider

If attending a live training, skip this section

Now that we have Modlishka up and running. Let’s get it configured with a target login provider. We’ll use Authentik to get an Okta like experience.

mkdir ~/Desktop/op/docker/authentik
cd ~/Desktop/op/docker/
echo "PG_PASS=dumbpassword" >> .env
echo "AUTHENTIK_SECRET_KEY=supersecretkeythatpaullikes" >> .env
echo "AUTHENTIK_ERROR_REPORTING__ENABLED=true" >> .env

Add the follow for emails…

# SMTP Host Emails are sent to
AUTHENTIK_EMAIL__HOST=mailhog
AUTHENTIK_EMAIL__PORT=1025
# Optionally authenticate (don't add quotation marks to your password)
AUTHENTIK_EMAIL__USERNAME=
AUTHENTIK_EMAIL__PASSWORD=
# Use StartTLS
AUTHENTIK_EMAIL__USE_TLS=false
# Use SSL
AUTHENTIK_EMAIL__USE_SSL=false
AUTHENTIK_EMAIL__TIMEOUT=10
# Email address authentik will send from, should have a correct @domain
AUTHENTIK_EMAIL__FROM=authentik@target.docker

Now we’ll merge their docker-compose.yml with ours (ref). We’ll start with the services.

    # `user: root` and the docker socket volume are optional.
    # See more for the docker socket integration here:
    # https://goauthentik.io/docs/outposts/integrations/docker
    # Removing `user: root` also prevents the worker from fixing the permissions
    # on the mounted folders, so when removing this make sure the folders have the correct UID/GID
    # (1000:1000 by default)
    user: root
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

      - ./authentik/certs:/certs
      - ./authentik/custom-templates:/templates
    env_file:

We also need to update our volumes:


volumes:
  database:
    driver: local
  redis:
    driver: local

Lets test it out.

sudo docker compose up

Now open http://auth.target.docker:9000/if/flow/initial-setup/. We should see a simple setup page.
