+# Login Captcha
+
+This plugin provides a captcha for the login page to enhance security.
+
+## Installation
+
+To install the plugin, run the following command:
+
+```bash
+npm i @adminforth/login-captcha
+```
+
+You will also need to install a captcha adapter. For example, to use the Cloudflare adapter, run:
+
+```bash
+npm i @adminforth/login-captcha-adapter-cloudflare
+```
+
+## Usage
+
+To use the plugin, add it to your user resource file. Here's an example:
+
+```ts template="./resources/adminuser.ts"
+// Import the plugin and adapter
+import CaptchaPlugin from "@adminforth/login-captcha";
+import CaptchaAdapterCloudflare from "@adminforth/captcha-adapter-cloudflare";
+
+...
+
+// Add the plugin to the `plugins` array
+plugins: [
+    new CaptchaPlugin({ 
+      captchaAdapter: new CaptchaAdapterCloudflare({
+        siteKey: "YOUR_SITE_KEY", // Replace with your site key
+        secretKey: "YOUR_SECRET_KEY", // Replace with your secret key
+      }),
+    }),
+]
+```
+
+## Result
