+## FreePass User ID Submodule
+
+[FreePass](https://freepass-login.com/introduction.html) is a common authentication service operated by Freebit Co., Ltd. Users with a FreePass account do not need to create a new account to use partner services. 
+
+# General Information
+
+Please contact FreePass before using this ID.
+
+```
+Module Name: FreePass Id System
+Module Type: User Id System
+Maintainer: [email protected]
+```
+
+## Building Prebid with FreePass ID Support
+
+First, make sure to add the FreePass ID submodule to your Prebid.js package with:
+
+```shell
+gulp build --modules=freepassIdSystem,userId
+```
+
+The following configuration parameters are available:
+
+```javascript
+pbjs.setConfig({
+    userSync: {
+        userIds: [{
+            name: 'freepassId',
+            params: {
+                freepassData: {
+                    commonId: 'fpcommonid123',
+                    userIp: '127.0.0.1'
+                }
+            }
+        }]
+    }
+});
+```
+
