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 Karakeep 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 create an application and provider pair. (Alternatively you can first create a provider separately, then create the application and connect it with the provider.)
    • 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://karakeep.company/api/auth/callback/custom.
      • 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.

Karakeep configuration​

Karakeep uses environment variables to configure OAuth. Add the following variables to the environment file for the Karakeep web container:

.env
NEXTAUTH_URL=https://karakeep.company
OAUTH_CLIENT_ID=<Client ID from authentik>
OAUTH_CLIENT_SECRET=<Client Secret from authentik>
OAUTH_WELLKNOWN_URL=https://authentik.company/application/o/<application_slug>/.well-known/openid-configuration
OAUTH_PROVIDER_NAME=authentik

If Karakeep already has local accounts that should sign in through authentik with the same email address, you can also set the following variable. Only enable this setting when you trust authentik as the OAuth provider for those account email addresses.

.env
OAUTH_ALLOW_DANGEROUS_EMAIL_ACCOUNT_LINKING=true

To make authentik the only login method for Karakeep, you can add the following variables:

.env
DISABLE_PASSWORD_AUTH=true
DISABLE_SIGNUPS=true
OAUTH_AUTO_REDIRECT=true

Restart the Karakeep server to apply the changes.

Configuration verification​

To confirm that authentik is properly configured with Karakeep, open Karakeep and click Sign in with authentik. You should be redirected to authentik, then returned to Karakeep after a successful login.
