# Enabling extended metadata checks for your repository

Learn how to enable extended metadata checks for detected secrets so alerts detected by secret scanning include additional information that help you assess and remediate leaks faster.

> \[!NOTE] トークンの拡張メタデータ チェックはパブリック プレビュー段階であり、変更される可能性があります。

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 [カスタム セキュリティ構成を作成する](/ja/code-security/how-tos/secure-at-scale/configure-organization-security/establish-complete-coverage/creating-a-custom-security-configuration) or [Enterprise 用のカスタム セキュリティ構成の作成](/ja/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 [リポジトリの有効性チェックの有効化](/ja/code-security/secret-scanning/enabling-secret-scanning-features/enabling-validity-checks-for-your-repository#enabling-validity-checks).
