# Overview
|
|
Captcha can be enabled for this home server. This file explains how to do that.
|
|
The captcha mechanism used is Google's ReCaptcha. This requires API keys from Google.
|
|
|
|
## Getting keys
|
|
|
|
Requires a site/secret key pair from:
|
|
|
|
<https://developers.google.com/recaptcha/>
|
|
|
|
Must be a reCAPTCHA v2 key using the "I'm not a robot" Checkbox option
|
|
|
|
## Setting ReCaptcha Keys
|
|
|
|
The keys are a config option on the home server config. If they are not
|
|
visible, you can generate them via `--generate-config`. Set the following value:
|
|
|
|
recaptcha_public_key: YOUR_SITE_KEY
|
|
recaptcha_private_key: YOUR_SECRET_KEY
|
|
|
|
In addition, you MUST enable captchas via:
|
|
|
|
enable_registration_captcha: true
|
|
|
|
## Configuring IP used for auth
|
|
|
|
The ReCaptcha API requires that the IP address of the user who solved the
|
|
captcha is sent. If the client is connecting through a proxy or load balancer,
|
|
it may be required to use the `X-Forwarded-For` (XFF) header instead of the origin
|
|
IP address. This can be configured using the `x_forwarded` directive in the
|
|
listeners section of the homeserver.yaml configuration file.
