> \[!NOTE] 扩展的令牌元数据检查功能处于公开预览中，并可能发生变化。
This article shows how you can enable extended metadata checks for individual repositories through repository settings. Alternatively, you can enable them at scale using **security configurations** at the organization or enterprise level. See [删除自定义安全配置](/zh/code-security/how-tos/secure-at-scale/configure-organization-security/establish-complete-coverage/creating-a-custom-security-configuration) or [为企业创建自定义安全配置](/zh/code-security/how-tos/secure-at-scale/configure-enterprise-security/establish-complete-coverage/creating-a-custom-security-configuration-for-your-enterprise).
## Prerequisites
Before enabling metadata checks, you need to ensure that validity checks are enabled for the repository. See [为存储库启用有效性检查](/zh/code-security/secret-scanning/enabling-secret-scanning-features/enabling-validity-checks-for-your-repository#enabling-validity-checks).
## Enabling extended metadata checks
1. 在 GitHub 上，导航到存储库的主页面。
2. 在仓库名称下，单击 “Settings”\*\*\*\*。 如果看不到“设置”选项卡，请选择“”下拉菜单，然后单击“设置”。
3. 在边栏的“Security”部分中，单击“ Advanced Security”\*\*\*\*。
4. Under "Secret Protection" and "Validity checks", to the right of "Extended metadata", click **Enable**.
