Integrate with Firezone

Support level: Community

What is Firezone?​

Firezone is an open-source remote access platform built on WireGuard®, a modern VPN protocol that's 4-6x faster than OpenVPN.

Preparation​

The following placeholders are used in this guide:

  • authentik.company is the FQDN of the authentik installation.
info

This documentation lists only the settings that you need to change from their default values. Be aware that any changes other than those explicitly mentioned in this guide could cause issues accessing your application.

authentik configuration​

Redirect URI changes in authentik 2026.5

In authentik versions earlier than 2026.5, all Redirect URIs are automatically treated as Authorization type. If you are using one of these older authentik versions, add only the Authorization URL to your Redirect URIs and do not configure a Post Logout URI.

To support the integration of Firezone with authentik, you need to create an application/provider pair in authentik.

Create an application and provider​

  1. Log in to authentik as an administrator and open the authentik Admin interface.

  2. Navigate to Applications > Applications and click New Application to open the application wizard.

    • Application: provide a descriptive name, an optional group for the type of application, the policy engine mode, and optional UI settings. Note the Slug value because it will be required later.
    • Choose a Provider type: select OAuth2/OpenID Connect as the provider type.
    • Configure the Provider: provide a name (or accept the auto-provided name), the authorization flow to use for this provider, and the following required configurations.
      • Note the Client ID and Client Secret values because they will be required later.
      • Add a Redirect URI of type Strict Authorization as https://app.firezone.dev/auth/oidc/callback.
      • Select any available signing key.
    • Configure Bindings (optional): you can create a binding (policy, group, or user) to manage the listing and access to applications on a user's Application Dashboard page.

  3. Click Submit to save the new application and provider.

Firezone configuration​

  1. Log in to the Firezone admin portal as an administrator.
  2. Navigate to Settings > Authentication.
  3. Click Add Provider and select OIDC.
  4. Configure the provider with the following values:
    • Name: enter a descriptive name, such as authentik. This name is shown to users on the sign-in page.
    • Authentication Context: select where users should be able to sign in with authentik.
    • Discovery Document URI: https://authentik.company/application/o/<application_slug>/.well-known/openid-configuration
    • Client ID: enter the client ID from authentik.
    • Client Secret: enter the client secret from authentik.
    • Email Verification: select Proof.
  5. Confirm that the Redirect URI shown by Firezone is https://app.firezone.dev/auth/oidc/callback.
  6. Click Verify Now and complete the authentication flow with authentik.
  7. After Firezone shows the provider as verified, click Save.

Firezone's universal OIDC provider does not sync users or groups. Create users in Firezone before they sign in with authentik, and create any groups that you need for Firezone access policies.

Configuration verification​

To verify that authentik is correctly integrated with Firezone, open Firezone and sign in with the authentik provider. A successful login redirects you back to Firezone.
