Authelia has a few config items that don't fit into their own area. This describes these options.


certificates_directory: /config/certs/
default_redirection_url: https://home.example.com:8080/
jwt_secret: v3ry_important_s3cr3t
theme: light



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).


string not required

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 they get 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 them 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.


string totp not required

Sets the default second factor method for users. This must be blank or one of the enabled methods. New users will by default have this method selected for them. In addition if this was configured to webauthn and a user had the totp method, and the totp method was disabled in the configuration, the users’ method would automatically update to the webauthn method.

Options are:

  • totp
  • webauthn
  • mobile_push
default_2fa_method: totp


string required

Important Note: This can also be defined using a secret which is strongly recommended especially for containerized deployments.

Defines the secret used to craft JWT tokens leveraged by the identity verification process. This can a random string. It’s strongly recommended this is a Random Alphanumeric String with 64 or more characters.


string light not required

There are currently 3 available themes for Authelia:

  • light (default)
  • dark
  • grey

To enable automatic switching between themes, you can set theme to auto. The theme will be set to either dark or light depending on the user’s system preference which is determined using media queries. To read more technical details about the media queries used, read the MDN.
