Integrate with Infisical

Support level: Community

What is Infisical?​

Infisical is an open source platform for managing secrets, certificates, and secure infrastructure access.

-- https://infisical.com/

Preparation​

The following placeholders are used in this guide:

  • infisical.company is the FQDN of the self-hosted Infisical installation. Infisical Cloud uses app.infisical.com for the US region and eu.infisical.com for the EU region.
  • 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.

Infisical requirements

OIDC SSO requires an Infisical Cloud (SaaS) Pro plan or a license for a self-hosted Infisical installation. Infisical also requires you to verify your organization's email domain before configuring SSO; domain verification is outside the scope of this guide.

For a self-hosted installation, ensure that AUTH_SECRET and SITE_URL are configured before setting up OIDC.

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 Infisical 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 is 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 the Redirect URI for your Infisical deployment with the type set to Strict Authorization:
        • Infisical Cloud US: https://app.infisical.com/api/v1/sso/oidc/callback
        • Infisical Cloud EU: https://eu.infisical.com/api/v1/sso/oidc/callback
        • Self-hosted Infisical: https://infisical.company/api/v1/sso/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.

Infisical configuration​

  1. Log in to Infisical as an organization administrator.
  2. Navigate to SSO & Provisioning and select the SSO tab.
  3. Click Add Provider, select OIDC, and click Continue.
  4. Configure the following settings:
    • Discovery Document URL: 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.
  5. Click Configure OIDC.

Configuration verification​

To confirm that authentik is properly configured with Infisical, log out and open Infisical. Click Continue with OIDC, enter an email address from the verified domain, and click Continue with OIDC again. Infisical should redirect you to authentik for authentication and then return you to Infisical.
