title: Configuration
---
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 Tabs from "@theme/Tabs";
import TabItem from "@theme/TabItem";
<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 dump_config
```
</TabItem>
<TabItem value="kubernetes" label="Kubernetes">
```
kubectl exec -it deployment/authentik-worker -c worker -- ak dump_config
```
</TabItem>
</Tabs>
## PostgreSQL Settings
- `AUTHENTIK_POSTGRESQL__HOST`: Hostname of your PostgreSQL Server
- `AUTHENTIK_POSTGRESQL__NAME`: Database name
- `AUTHENTIK_POSTGRESQL__USER`: Database user
- `AUTHENTIK_POSTGRESQL__PORT`: Database port, defaults to 5432
- `AUTHENTIK_POSTGRESQL__PASSWORD`: Database password, defaults to the environment variable `POSTGRES_PASSWORD`
- `AUTHENTIK_POSTGRESQL__USE_PGBOUNCER`: Adjust configuration to support connection to PgBouncer
- `AUTHENTIK_POSTGRESQL__USE_PGPOOL`: Adjust configuration to support connection to Pgpool
- `AUTHENTIK_POSTGRESQL__SSLMODE`: Strictness of ssl verification. Defaults to `"verify-ca"`
- `AUTHENTIK_POSTGRESQL__SSLROOTCERT`: CA root for server ssl verification
- `AUTHENTIK_POSTGRESQL__SSLCERT`: Path to x509 client certificate to authenticate to server
- `AUTHENTIK_POSTGRESQL__SSLKEY`: Path to private key of `SSLCERT` certificate
All PostgreSQL settings, apart from `USE_PGBOUNCER` and `USE_PGPOOL`, support hot-reloading. Adding and removing read replicas doesn't support hot-reloading.
### Read replicas
You can configure additional read replica databases that are used only for read operations. To configure authentik to use replicas, add the settings below to your [configuration file](./configuration.mdx#set-your-environment-variables). If you have multiple replicas, add additional settings for each replica, replacing the default `0` with a unique value for each additional replica.
If read replicas are configured, the main database is not used for reads. If you'd like the main database to be included for reads, add it as a read replica.
The same PostgreSQL settings as described above are used for each read replica.
- `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`
Note that `USE_PGBOUNCER` and `USE_PGPOOL` are inherited from the main database configuration and are _not_ overridable on read replicas.
## Redis Settings
- `AUTHENTIK_REDIS__HOST`: Redis server host when not using configuration URL
- `AUTHENTIK_REDIS__PORT`: Redis server port when not using configuration URL
- `AUTHENTIK_REDIS__DB`: Redis server database when not using configuration URL

Requests directly coming from one an address within a CIDR specified here are able to set proxy headers, such as `X-Forwarded-For`. Requests coming from other addresses will not be able to set these headers.
## Media Storage Settings
These settings affect where media files are stored. Those files include applications and sources icons. By default, they are stored on disk in the `/media` directory of the authentik container. S3 storage is also supported.
- `AUTHENTIK_STORAGE__MEDIA__BACKEND`: Where to store files. Valid values are `file` and `s3`. For `file` storage, files are stored in a `/media` directory in the container. For `s3`, see below.

## 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`
Log level for the server and worker containers. Possible values: `debug`, `info`, `warning`, `error`.
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`
Path to the GeoIP City database. Defaults to `/geoip/GeoLite2-City.mmdb`. If the file is not found, authentik will skip GeoIP support.
### `AUTHENTIK_EVENTS__CONTEXT_PROCESSORS__ASN`
Path to the GeoIP ASN database. Defaults to `/geoip/GeoLite2-ASN.mmdb`. If the file is not found, authentik will skip GeoIP support.
### `AUTHENTIK_DISABLE_UPDATE_CHECK`
Disable the inbuilt update-checker. Defaults to `false`.
### `AUTHENTIK_ERROR_REPORTING`
- `AUTHENTIK_ERROR_REPORTING__ENABLED`
Enable error reporting. Defaults to `false`.
Error reports are sent to https://sentry.io and are used for debugging and general feedback. Anonymous performance data is also sent.
- `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`
- `AUTHENTIK_EMAIL__HOST`
Default: `localhost`
- `AUTHENTIK_EMAIL__PORT`
Default: `25`
- `AUTHENTIK_EMAIL__USERNAME`

- `AUTHENTIK_EMAIL__USE_TLS`
Default: `false`
- `AUTHENTIK_EMAIL__USE_SSL`
Default: `false`
- `AUTHENTIK_EMAIL__TIMEOUT`
Default: `10`
- `AUTHENTIK_EMAIL__FROM`
Default: `authentik@localhost`
Email address authentik will send from, should have a correct @domain
To change the sender's display name, use a format like `Name <account@domain>`.
### `AUTHENTIK_OUTPOSTS`
- `AUTHENTIK_OUTPOSTS__CONTAINER_IMAGE_BASE`
Placeholders:
- `%(type)s`: Outpost type; proxy, ldap, etc
- `%(version)s`: Current version; 2021.4.1
- `%(build_hash)s`: Build hash if you're running a beta version
Placeholder for outpost docker images. Default: `ghcr.io/goauthentik/%(type)s:%(version)s`.
- `AUTHENTIK_OUTPOSTS__DISCOVER`
Configure the automatic discovery of integrations. Defaults to `true`.
By default, the following is discovered:
- Kubernetes in-cluster config
- Kubeconfig
- Existence of a docker socket
### `AUTHENTIK_LDAP__TASK_TIMEOUT_HOURS` <span class="badge badge--version">authentik 2023.1+</span>
Timeout in hours for LDAP synchronization tasks.
Defaults to `2`.
### `AUTHENTIK_LDAP__PAGE_SIZE` <span class="badge badge--version">authentik 2023.6.1+</span>
Page size for LDAP synchronization. Controls the number of objects created in a single task.
Defaults to `50`.
### `AUTHENTIK_LDAP__TLS__CIPHERS` <span class="badge badge--version">authentik 2022.7+</span>

Defaults to `null`.
### `AUTHENTIK_REPUTATION__EXPIRY` <span class="badge badge--version">authentik 2023.8.2+</span>
Configure how long reputation scores should be saved for in seconds. Note that this is different than [`AUTHENTIK_REDIS__CACHE_TIMEOUT_REPUTATION`](#redis-settings), as reputation is saved to the database every 5 minutes.
Defaults to `86400`.
### `AUTHENTIK_SESSION_STORAGE` <span class="badge badge--version">authentik 2024.4+</span>
Configure if the sessions are stored in the cache or the database. Defaults to `cache`. Allowed values are `cache` and `db`. Note that changing this value will invalidate all previous sessions.
### `AUTHENTIK_WEB__WORKERS` <span class="badge badge--version">authentik 2022.9+</span>
Configure how many gunicorn worker processes should be started (see https://docs.gunicorn.org/en/stable/design.html).
Defaults to 2. A value below 2 workers is not recommended. In environments where scaling with multiple replicas of the authentik server is not possible, this number can be increased to handle higher loads.
### `AUTHENTIK_WEB__THREADS` <span class="badge badge--version">authentik 2022.9+</span>
Configure how many gunicorn threads a worker processes should have (see https://docs.gunicorn.org/en/stable/design.html).
Defaults to 4.
### `AUTHENTIK_WORKER__CONCURRENCY` <span class="badge badge--version">authentik 2023.9+</span>
Configure Celery worker concurrency for authentik worker (see https://docs.celeryq.dev/en/latest/userguide/configuration.html#worker-concurrency). This essentially defines the number of worker processes spawned for a single worker.
Defaults to 2.
## System settings <span class="badge badge--version">authentik 2024.2+</span>
Additional settings are configurable using the Admin interface, under **System** -> **Settings** or using the API.
## Custom python settings
To modify additional settings further than the options above allow, you can create a custom Python file and mount it to `/data/user_settings.py`. This file will be loaded on startup by both the server and the worker. All default settings are [here](https://github.com/goauthentik/authentik/blob/main/authentik/root/settings.py)
:::caution
Using these custom settings is not supported and can prevent your authentik instance from starting. Use with caution.
