Authelia sends messages to users in order to verify their identity.

You must configure exactly one notification provider: either filesystem or smtp. These providers are mutually exclusive - you cannot configure both at the same time.
This section describes the individual configuration options.
{{< confkey type="boolean" default="false" required="no" >}}
{{< callout context="danger" title="Warning" icon="outline/alert-octagon" >}} It is highly recommend you address any issues/errors generated by startup checks rather than disabling the startup checks. By disabling the startup checks you won't know that notifications don't send until you attempt to send a notification. {{< /callout >}}
The two notification providers have a startup check which validates the specified provider configuration and verifies the provider can send notifications:
disable_startup_check option.{{< confkey type="string" required="no" >}}
{{< callout context="note" title="Note" icon="outline/info-circle" >}} You may configure this directory and add only add the templates you wish to override, any templates not supplied in this folder will utilize the default templates. {{< /callout >}}
This option allows the administrator to set a path to a directory where custom templates for notifications can be found. The specifics are located in the Notification Templates Reference Guide.
The filesystem provider.
The smtp provider.
