-## Obtaining Authentication Object Version Information
-
-### How to Develop
-
-1. Apply for the permission.<br> Configure the **ohos.permission.ACCESS_BIOMETRIC** permission in **requestPermissions** in the **module.json5** file. For more information, see [module.json5](../quick-start/module-configuration-file.md).
-
-2. Use [getVersion](../reference/apis/js-apis-useriam-userauth.md#useriam_userauthgetversion9) to obtain the version information.
-
-    ```js
-    import userIAM_userAuth from '@ohos.userIAM.userAuth';
-
-    // Obtain version information.
-    try {
-        let version = userIAM_userAuth.getVersion();
-        console.info("auth version = " + version);
-    } catch (error) {
-        console.info("get version failed, error = " + error);
-    }
-    ```
