Integrate with Vaultwarden

Support level: Community

What is Vaultwarden​

Vaultwarden is an alternative server implementation of the Bitwarden Client API, written in Rust and compatible with official Bitwarden clients, perfect for self-hosted deployment where running the official resource-heavy service might not be ideal.

Preparation​

The following placeholders are used in this guide:

  • vaultwarden.company is the FQDN of the Vaultwarden installation.
  • authentik.company is the FQDN of the authentik installation.
note

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​

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

Create an application and provider in authentik​

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

  2. Navigate to Applications > Applications and click Create with Provider 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.
    • 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,Client Secret, and slug values because they will be required later.
      • Set a Strict redirect URI to https://vaultwarden.company/identity/connect/oidc-signin.
      • 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 My applications page.

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

Vaultwarden configuration​

To configure authentik with Vaultwarden, you must add the following environment variables:

SSO_ENABLED=true
SSO_AUTHORITY=https://authentik.company/application/o/<application_slug>
SSO_CLIENT_ID=<client_id>
SSO_CLIENT_SECRET=<client_secret>
SSO_SCOPES=email profile
SSO_ALLOW_UNKNOWN_EMAIL_VERIFICATION=false
SSO_CLIENT_CACHE_EXPIRATION=0
SSO_ONLY=false # Disable email + master-password login and require SSO.
SSO_SIGNUPS_MATCH_EMAIL=true # Associate first-time SSO users to existing local accounts with the same email.

Then, restart the Vaultwarden server to apply the changes.
