# Miscellaneous

Here are the main customizable options in Authelia.

## Host & Port

`optional: true`

Defines the address and port to listen on.

```yaml
host: 0.0.0.0
port: 9091
```

Note: If utilising an IPv6 literal address it must be enclosed by square brackets and quoted:

```yaml
host: "[fd00:1111:2222:3333::1]"
```

## TLS

`optional: true`

Authelia can use TLS. Provide the certificate and the key with the
following configuration options:

```yaml
tls_key: /config/ssl/key.pem
tls_cert: /config/ssl/cert.pem
```

## Certificates Directory

`optional: true`

This option defines the location of additional certificates to load into the trust chain specifically for Authelia.
This currently affects both the SMTP notifier and the LDAP authentication backend. The certificates should all be in the
PEM format and end with the extension `.pem`, `.crt`, or `.cer`. You can either add the individual certificates public key 
or the CA public key which signed them (don't add the private key).


## Log

### Log level

`optional: true`

Defines the level of logs used by Authelia. This level can be set to
`trace`, `debug` or `info`. When setting log_level to `trace`, you will
generate a large amount of log entries and expose the `/debug/vars` and
`/debug/pprof/` endpoints which should not be enabled in production.

```yaml
log_level: debug
```

### Log format

`optional: true`

Defines the format of the logs written by Authelia.
This format can be set to `json` or `text`.

```yaml
log_format: json
```

#### JSON format
```
{"level":"info","msg":"Logging severity set to info","time":"2020-01-01T00:00:00+11:00"}
{"level":"info","msg":"Authelia is listening for non-TLS connections on 0.0.0.0:9091","time":"2020-01-01T00:00:00+11:00"}
```
#### Text format
```
time="2020-01-01T00:00:00+11:00" level=info msg="Logging severity set to info"
time="2020-01-01T00:00:00+11:00" level=info msg="Authelia is listening for non-TLS connections on 0.0.0.0:9091"
```

### Log file path

`optional: true`

Logs can be stored in a file when file path is provided. Otherwise logs
are written to standard output. When setting the log_level to `debug` or
`trace` this will generate large amount of log entries.
Administrators will need to ensure that they rotate and/or truncate the
logs over time to prevent significant long-term disk usage.

```yaml
log_file_path: /config/authelia.log
```

## JWT Secret

`optional: false`

Defines the secret used to craft JWT tokens leveraged by the identity
verification process. This can also be defined using a [secret](./secrets.md).

```yaml
jwt_secret: v3ry_important_s3cr3t
```

## Default redirection URL

`optional: true`

The default redirection URL is the URL where users are redirected when Authelia
cannot detect the target URL where the user was heading.

In a normal authentication workflow, a user tries to access a website and she
gets redirected to the sign-in portal in order to authenticate. Since the user
initially targeted a website, the portal knows where the user was heading and
can redirect her after the authentication process.
However, when a user visits the sign in portal directly, the portal considers
the targeted website is the portal. In that case and if the default redirection URL
is configured, the user is redirected to that URL. If not defined, the user is not
redirected after authentication.
