## 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.

## authentik configuration

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

### Create custom scope mapping

Vaultwarden either requires the email scope to return a true value for whether the email address is verified, or no value at all. As of [authentik 2025.10](https://docs.goauthentik.io/releases/2025.10/#default-oauth-scope-mappings) the default behavior is to return `email_verified: False`, so a custom scope mapping is required for Vaultwarden to allow authentication.

1. Log in to authentik as an administrator and open the authentik Admin interface.
2. Navigate to **Customization** > **Property Mappings** and click **Create**.
    - **Select type**: select **Scope Mapping**.
    - **Configure the Scope Mapping**: Provide a descriptive name (e.g. `Vaultwarden Email Scope`), and an optional description.
        - **Scope name**: `email`
        - **Expression**:

        ```python showLineNumbers
        return {
            "email": request.user.email,
            "email_verified": True
        }
        ```

3. Click **Finish** to save the property mapping.

### 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 **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.
    - **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.
        - Under **Advanced protocol settings**:
            - Set **Access token validity** to more than 5 minutes.
            - Ensure the `offline_access` scope mapping is available by adding `authentik default OAuth Mapping: OpenID 'offline_access'` to the selected scopes.
            - Remove the `authentik default OAuth Mapping: OpenID 'email'` scope, and add the custom scope mapping you created above.
    - **Configure Bindings** _(optional)_: you can create a [binding](/docs/add-secure-apps/bindings-overview/) (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 Vaultwarden to use authentik, add the following environment variables to your Vaultwarden deployment:

```yaml
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 offline_access
SSO_ALLOW_UNKNOWN_EMAIL_VERIFICATION=false
SSO_CLIENT_CACHE_EXPIRATION=0
SSO_ONLY=false # Set to true to disable email+master password login and require SSO
SSO_SIGNUPS_MATCH_EMAIL=true # Match first SSO login to existing account by email
```

Then restart Vaultwarden to apply the changes.

## Configuration verification

To verify the integration of authentik with Vaultwarden, log out of Vaultwarden, then on the login page enter a verified email and click **Use single sign-on**.
