Block Logins with Cloudflare helps protect your WordPress site from brute-force attacks by blocking IPs at the Cloudflare firewall after a configurable number of failed login attempts.
<ul>
<li>Block IPs via Cloudflare after X failed login attempts</li>
<li>Block IPs that generate excessive 404 responses (bots and scanners)</li>
<li>Block IPs attacking via XML-RPC with intelligent detection</li>
<li>Automatic unblocking after a configurable duration</li>
<li>Whitelist IPs to never block or track them (supports IPv6 CIDR ranges)</li>
<li>View and manually unblock blocked IPs from the admin</li>
<li>Block source tracking — see whether each IP was blocked via login, XML-RPC, or 404</li>
<li>Sync existing Cloudflare blocks into the local blocked IPs list</li>
<li>Secure settings page with Cloudflare API token validation</li>
<li>Hourly cron job for automatic maintenance</li>
</ul>
<h3>External Services</h3>
This plugin relies on the Cloudflare API to function. It communicates with Cloudflare’s external servers to block IP addresses at the firewall level.
What is the Cloudflare API and what is it used for? 
The Cloudflare API is a RESTful service provided by Cloudflare, Inc. that allows programmatic management of Cloudflare firewall rules. This plugin uses it to automatically block and unblock IP addresses based on failed login attempts, XML-RPC attacks, and 404 scanning activity.
What data is sent and when? 
The plugin sends the following data to Cloudflare’s API servers:
<ol>
<li>
During settings validation (when you save Cloudflare credentials):
<ul>
<li>Your Cloudflare API token (for verification)</li>
<li>Endpoint: <code>https://api.cloudflare.com/client/v4/user/tokens/verify</code></li>
</ul>
</li>
<li>
When blocking an IP (after a threshold is reached):
<ul>
<li>The IP address to be blocked</li>
<li>Your Cloudflare email address and API key/token</li>
<li>Your Cloudflare Zone ID</li>
<li>A note describing the reason for the block</li>
<li>Endpoint: <code>https://api.cloudflare.com/client/v4/zones/{zone_id}/firewall/access_rules/rules</code></li>
</ul>
</li>
<li>
When syncing from Cloudflare (on demand):
<ul>
<li>Fetches existing firewall rules from your Cloudflare zone</li>
<li>Endpoint: <code>https://api.cloudflare.com/client/v4/zones/{zone_id}/firewall/access_rules/rules</code></li>
</ul>
</li>
</ol>
No personally identifiable information about your WordPress users is transmitted. Only IP addresses are sent to Cloudflare.
Service provider information: 
– Service: Cloudflare API 
– Provider: Cloudflare, Inc. 
– Terms of Service: https://www.cloudflare.com/terms/ 
– Privacy Policy: https://www.cloudflare.com/privacypolicy/ 
– API Documentation: https://developers.cloudflare.com/api/
Required for functionality: 
This plugin requires a Cloudflare account and will not function without valid Cloudflare API credentials. The external API calls are essential to the plugin’s core functionality.

This is awesome plugin!
It has all the features I need and is very easy to use.

Awesome!

長年、SiteGuardを使っていましたが、たまにログインできなくなってプラグインをサーバーから削除とかしたりだったので、こちらのプラグインを使い始めました。
設定画面もわかりやすく、作動も安定していて、ログイン試行履歴とかも見れます（結構不正ログインされようとしているのがわかって楽しい）、随時他のサイトのセキュリティプラグインもこちらに切り替えていこうと思っています。感謝感謝

とても良い
