Captcha can be enabled for this web client / 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 public/private key pair from:
https://developers.google.com/recaptcha/
Setting Private ReCaptcha Key
-----------------------------
The private key is a config option on the home server config. If it is not
visible, you can generate it via --generate-config. Set the following value:
recaptcha_private_key: YOUR_PRIVATE_KEY
In addition, you MUST enable captchas via:
enable_registration_captcha: true
Setting Public ReCaptcha Key
----------------------------
The web client will look for the global variable webClientConfig for config
options. You should put your ReCaptcha public key there like so:
webClientConfig = {
useCaptcha: true,
recaptcha_public_key: "YOUR_PUBLIC_KEY"
}
This should be put in webclient/config.js which is already .gitignored, rather
than in the web client source files. You MUST set useCaptcha to true else a
ReCaptcha widget will not be generated.
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 as an option on the home server like so:
captcha_ip_origin_is_x_forwarded: true
