This page details all the authentik configuration options that you can set via environment variables.

## About authentik configurations

:::info
The double-underscores are intentional, as all these settings are translated to YAML internally, and a double-underscore indicates the next level (a subsetting).
:::

All of these variables can be set to values, but you can also use a URI-like format to load values from other places:

- `env://<name>` Loads the value from the environment variable `<name>`. Fallback can be optionally set like `env://<name>?<default>`
- `file://<name>` Loads the value from the file `<name>`. Fallback can be optionally set like `file://<name>?<default>`

## Set your environment variables

import TabItem from "@theme/TabItem";
import Tabs from "@theme/Tabs";

<Tabs groupId="platform">
  <TabItem value="docker-compose" label="Docker Compose" default>
    If you are using Docker Compose, edit your <code>.env</code> file to append any keys that you want to add, and then run the following command to apply them:

    ```
    docker compose up -d
    ```

  </TabItem>
  <TabItem value="kubernetes" label="Kubernetes">
    If you are running in Kubernetes, edit your <code>values.yaml</code> file to append any keys that you want to add, and then run the following commands to apply:

    ```
    helm repo update
    helm upgrade --install authentik authentik/authentik -f values.yaml
    ```

  </TabItem>

</Tabs>

## Verify your configuration settings

To check if your config has been applied correctly, you can run the following command to output the full config:

<Tabs groupId="platform">
  <TabItem value="docker-compose" label="Docker Compose" default>

    ```
    docker compose run --rm worker ak dump_config
    ```

  </TabItem>
  <TabItem value="kubernetes" label="Kubernetes">

    ```
    kubectl exec -it deployment/authentik-worker -c worker -- ak dump_config
    ```

  </TabItem>

</Tabs>

## PostgreSQL settings

authentik requires PostgreSQL for application data, configuration, sessions, and background task coordination.

Use the settings in this section to configure:

- the primary PostgreSQL connection
- TLS/SSL settings for PostgreSQL
- connection behavior and pooler compatibility
- optional read replicas

For more information, see the PostgreSQL upgrade guides for [Docker Compose](../../troubleshooting/postgres/upgrade_docker.md) and [Kubernetes](../../troubleshooting/postgres/upgrade_kubernetes.md). For backup guidance, see [Backup and restore](../../sys-mgmt/ops/backup-restore.md).

### Connection settings

These settings define the primary database connection used for writes and reads, unless you've set up read replicas.

- `AUTHENTIK_POSTGRESQL__HOST`

    Hostname or IP address of the PostgreSQL server.

- `AUTHENTIK_POSTGRESQL__PORT`

    Port on which PostgreSQL is listening.

    Default: `5432`

- `AUTHENTIK_POSTGRESQL__USER`

    PostgreSQL username used by authentik to authenticate.

- `AUTHENTIK_POSTGRESQL__PASSWORD`

    PostgreSQL password used by authentik to authenticate.

    If unset, authentik falls back to `POSTGRES_PASSWORD`. This fallback exists for the default Docker Compose setup and should not be relied on in more complex deployments.

- `AUTHENTIK_POSTGRESQL__NAME`

    Name of the PostgreSQL database to use.

:::info Hot-reloading
The `AUTHENTIK_POSTGRESQL__HOST`, `AUTHENTIK_POSTGRESQL__PORT`, `AUTHENTIK_POSTGRESQL__USER`, and `AUTHENTIK_POSTGRESQL__PASSWORD` settings support hot-reloading and can be changed without restarting authentik. However, adding or removing read replicas requires a restart.
:::

### TLS/SSL settings

Use these settings when your PostgreSQL server requires TLS/SSL or mutual TLS.

- `AUTHENTIK_POSTGRESQL__SSLMODE`

    Controls how TLS/SSL is used and verified for PostgreSQL connections.

    Default: `verify-ca`
    - `disable`: No SSL is used.
    - `allow`: Use SSL if available, but don't perform verification.
    - `prefer`: Attempt an SSL connection first, fall back to non-SSL if it fails.
    - `require`: Require an SSL connection, but without certificate verification.
    - `verify-ca`: Require SSL and verify that the server certificate is signed by a trusted CA.
    - `verify-full`: Require SSL, verify the CA, and verify that the server hostname matches the certificate.

- `AUTHENTIK_POSTGRESQL__SSLROOTCERT`

    Path to the CA certificate file used to verify the PostgreSQL server certificate.

    Required for `verify-ca` and `verify-full` modes.

- `AUTHENTIK_POSTGRESQL__SSLCERT`

    Path to the client certificate file.

    Required only if PostgreSQL is configured for mutual TLS and requires client certificates.

- `AUTHENTIK_POSTGRESQL__SSLKEY`

    Path to the private key corresponding to `AUTHENTIK_POSTGRESQL__SSLCERT`.

For more detail, see [Django's PostgreSQL documentation](https://docs.djangoproject.com/en/stable/ref/databases/#postgresql-connection-settings) and the [PostgreSQL `libpq` SSL documentation](https://www.postgresql.org/docs/current/libpq-ssl.html#LIBPQ-SSL-PROTECTION).

### Connection management

These settings control connection persistence and behavior, which is particularly important when using a connection pooler like PgBouncer or Pgpool.

- `AUTHENTIK_POSTGRESQL__CONN_MAX_AGE`

    Maximum age of a database connection in seconds.
    - `0` (default): Connections are closed after each request.
    - greater than `0`: Enables persistent connections, with the value defining the maximum lifetime.
    - `None`: Unlimited persistence. Use with caution, especially with connection poolers.

    In session pool mode, if the pooler drops its backend connection while the client connection remains open, the connection may not be released as expected. See [Django's documentation on persistent connections](https://docs.djangoproject.com/en/stable/ref/databases/#persistent-connections).

- `AUTHENTIK_POSTGRESQL__CONN_HEALTH_CHECKS`

    Enables health checks on persistent connections before reuse.

    Default: `false`

    This helps avoid errors caused by stale connections that were closed by PostgreSQL, a proxy, or a connection pooler. See [Django's documentation](https://docs.djangoproject.com/en/stable/ref/settings/#conn-health-checks).

- `AUTHENTIK_POSTGRESQL__DISABLE_SERVER_SIDE_CURSORS`

    Disables server-side cursors.

    Default: `false`

    Set this to `true` when using transaction-based pooling, or when you encounter cursor-related errors behind a pooler. Server-side cursors maintain state across queries and are not compatible with transaction pooling. See [Django's documentation](https://docs.djangoproject.com/en/stable/ref/databases/#transaction-pooling-and-server-side-cursors).

### Advanced Settings

- `AUTHENTIK_POSTGRESQL__DEFAULT_SCHEMA`

    The name of the database schema for authentik to use. Defaults to `public`.

    This can only be set before authentik starts for the first time. If you use a custom schema:
    - the schema must already exist
    - the PostgreSQL user must have permission to use it
    - the user's `search_path` must include that schema

- `AUTHENTIK_POSTGRESQL__CONN_OPTIONS`

    Additional `libpq` connection parameters for the primary database connection.

    A list of supported parameter keywords can be found in the [PostgreSQL documentation](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS).
    - Parameters passed with this setting will override those passed with other settings.
    - These parameters are not applied to read replicas.
    - The value must be a base64-encoded JSON dictionary.

### Read replicas

You can configure additional read replica databases to distribute database load and improve performance. When read replicas are configured, authentik automatically routes query operations between the primary database (for writes) and read replica databases (for queries).

By default, the primary database won't be used for queries when read replicas are available. If you want the primary database to also handle queries, add it as a read replica.

Each replica uses the same setting structure as the primary connection, but under `READ_REPLICAS`.

For the first replica, use index `0`:

- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__HOST`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__NAME`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__USER`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__PORT`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__PASSWORD`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__SSLMODE`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__SSLROOTCERT`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__SSLCERT`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__SSLKEY`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__CONN_MAX_AGE`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__CONN_HEALTH_CHECKS`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__DISABLE_SERVER_SIDE_CURSORS`
- `AUTHENTIK_POSTGRESQL__READ_REPLICAS__0__CONN_OPTIONS`

Use index `1`, `2`, and so on for additional replicas.

- `AUTHENTIK_POSTGRESQL__REPLICA_CONN_OPTIONS`

    Additional `libpq` connection parameters for all read replica connections.

    A list of supported keywords can be found in the [PostgreSQL documentation](https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS).
    - Parameters passed with this setting will override those passed with other settings.
    - The value must be a base64-encoded JSON dictionary.

### Using a PostgreSQL Connection Pooler

If authentik connects through a pooler such as PgBouncer or Pgpool, review these settings carefully:

- `AUTHENTIK_POSTGRESQL__CONN_MAX_AGE`

    Session-based pooling can behave poorly with unlimited persistent connections (`null`). If the pooler drops its backend connection while the client connection remains open, the connection may not be released as expected.

    To avoid this, either:
    - use transaction pooling, or
    - set `CONN_MAX_AGE` lower than the timeout that causes backend connections to be dropped, including `0` to disable persistent connections

- `AUTHENTIK_POSTGRESQL__DISABLE_SERVER_SIDE_CURSORS`

    When using transaction pooling, set this to `true`. Server-side cursors keep state across queries and will break when subsequent queries are sent over different backend connections.

### Recommended starting points

These are good starting points for common deployments:

- Direct PostgreSQL connection:
    - leave `AUTHENTIK_POSTGRESQL__CONN_MAX_AGE` as `0`
    - leave `AUTHENTIK_POSTGRESQL__DISABLE_SERVER_SIDE_CURSORS` as `false`
- PgBouncer or Pgpool in transaction mode:
    - set `AUTHENTIK_POSTGRESQL__DISABLE_SERVER_SIDE_CURSORS=true`
    - keep `AUTHENTIK_POSTGRESQL__CONN_MAX_AGE=0` unless you have a reason to change it
- TLS-secured PostgreSQL:
    - keep `AUTHENTIK_POSTGRESQL__SSLMODE=verify-ca` or use `verify-full` if hostname verification is available

### Deprecated Settings

- `AUTHENTIK_POSTGRESQL__USE_PGBOUNCER`

    Deprecated. Use the settings described in [Using a PostgreSQL Connection Pooler](#using-a-postgresql-connection-pooler) instead.

- `AUTHENTIK_POSTGRESQL__USE_PGPOOL`

## authentik settings

### `AUTHENTIK_SECRET_KEY`

Secret key used for cookie signing. Changing this will invalidate active sessions.

:::caution
Prior to 2023.6.0 the secret key was also used for unique user IDs. When running a pre-2023.6.0 version of authentik the key should _not_ be changed after the first install.
:::

### `AUTHENTIK_LOG_LEVEL`

Starting with 2021.12.3, you can also set the log level to `trace`. This has no effect on the core authentik server, but shows additional messages for the embedded outpost.

:::danger
Setting the log level to `trace` will include sensitive details in logs, so it shouldn't be used in most cases.

Logs generated with `trace` should be treated with care as they can give others access to your instance, and can potentially include things like session cookies to authentik **and other pages**.
:::

Defaults to `info`.

### `AUTHENTIK_COOKIE_DOMAIN`

Which domain the session cookie should be set to. By default, the cookie is set to the domain authentik is accessed under.

### `AUTHENTIK_EVENTS__CONTEXT_PROCESSORS__GEOIP`

- `AUTHENTIK_ERROR_REPORTING__SENTRY_DSN`

    Sets the DSN for the Sentry API endpoint.

    When error reporting is enabled, the default Sentry DSN will allow the authentik developers to receive error reports and anonymous performance data, which is used for general feedback about authentik, and in some cases, may be used for debugging purposes.

    Users can create their own hosted Sentry account (or self-host Sentry) and opt to collect this data themselves.

- `AUTHENTIK_ERROR_REPORTING__ENVIRONMENT`

    The environment tag associated with all data sent to Sentry. Defaults to `customer`.

    When error reporting has been enabled to aid in debugging issues, this should be set to a unique value, such as an email address.

- `AUTHENTIK_ERROR_REPORTING__SEND_PII`

    Whether or not to send personal data, like usernames. Defaults to `false`.

- `AUTHENTIK_ERROR_REPORTING__EXTRA_ARGS`

    Base64-encoded sentry_init arguments. See [Sentry's documentation](https://docs.sentry.io/platforms/python/configuration/options/) for available options.

### `AUTHENTIK_EMAIL`

The `AUTHENTIK_EMAIL` settings are used to configure SMTP email delivery from authentik.

These global email settings are used for administrator notifications, release and configuration alerts, [notification rules](../../sys-mgmt/events/notifications.md), and any [Email stage](../../add-secure-apps/flows-stages/stages/email/) configured to use global settings.

For complete setup examples, testing instructions, and TLS guidance, see the [Email configuration guide](../email.mdx).
