Sobre a verificação de segredo

O GitHub verifica repositórios em busca de tipos de segredos conhecidos a fim de impedir o uso fraudulento de segredos que sofreram commit acidentalmente.

Quem pode usar esse recurso?

Os Alertas de verificação de segredo para parceiros são executados automaticamente em repositórios públicos e pacotes npm públicos para notificar os provedores de serviço sobre os segredos vazados do

As Alertas de verificação de segredo para usuários estão disponíveis gratuitamente para todos os repositórios públicos.. As organizações que usam o GitHub Enterprise Cloud com uma licença do GitHub Advanced Security também podem habilitar alertas de verificação de segredo para usuários em seus repositórios privados e internos. Para obter mais informações, confira "Sobre a verificação de segredo" e "Sobre a Segurança Avançada do GitHub".

Para obter informações sobre como é possível testar o GitHub Enterprise com o GitHub Advanced Security de forma gratuita, confira “Configurar uma versão de avaliação do GitHub Enterprise Cloud” e “Como configurar uma avaliação gratuita do GitHub Advanced Security” na documentação do GitHub Enterprise Cloud.

If your project communicates with an external service, you might use a token or private key for authentication. Tokens and private keys are examples of secrets that a service provider can issue. If you check a secret into a repository, anyone who has read access to the repository can use the secret to access the external service with your privileges. We recommend that you store secrets in a dedicated, secure location outside of the repository for your project.

Secret scanning will scan your entire Git history on all branches present in your GitHub repository for secrets.

Additionally, secret scanning scans:

  • Descriptions and comments in issues
  • Titles, descriptions, and comments, in open and closed historical issues
  • Titles, descriptions, and comments in pull requests
  • Titles, descriptions, and comments in GitHub Discussions
  • Wikis

This additional scanning is free for public repositories.

Note: The scanning of content in pull requests, GitHub Discussions, and wikis is currently in beta and subject to change.

Secret scanning is available on in two forms:

  1. Secret scanning alerts for partners. Runs automatically on all public repositories and public npm packages. Service providers can partner with GitHub to provide their secret formats for scanning, hence the term "partners." To find out about our partner program, see "Secret scanning partner program." Any strings that match patterns that were provided by secret scanning partners are reported directly to the relevant partner. For more information, see the "About secret scanning alerts for partners" section below.

  2. Secret scanning alerts for users. These alerts are reported on The following users can enable and configure additional scanning:

    • Owners of repositories on, on any public repositories they own.
    • Organizations owning public repositories, on any of these repositories.
    • Organizations using GitHub Enterprise Cloud, on any public repositories (for free), and on any private and internal repositories, when you have a license for GitHub Advanced Security.

Any strings that match patterns provided by secret scanning partners, by other service providers, or defined by you or your organization, are reported as alerts in the Security tab of repositories. If a string in a public repository matches a partner pattern, it is also reported to the partner. For more information, see the "About secret scanning alerts for users" section below.

You can audit the actions taken in response to secret scanning alerts using GitHub tools. For more information, see "Auditing security alerts."

You can also enable secret scanning as a push protection for a repository or an organization. When you enable this feature, secret scanning prevents contributors from pushing code with a detected secret. To proceed, contributors must either remove the secret(s) from the push or, if needed, bypass the protection. Admins can also specify a custom link that is displayed to the contributor when a push is blocked; the link can contain resources specific to the organization to aid contributors. For more information, see "Push protection for repositories and organizations."

Additionally, push protection for users automatically protects you from accidentally committing secrets to public repositories, regardless of whether the repository has secret scanning enabled. Push protection for users is on by default, but you can disable the feature at any time through your personal account settings. For more information, see "Push protection for users."

Note: When you fork a repository with secret scanning or push protection enabled, these features are not enabled by default on the fork. You can enable secret scanning or push protection on the fork the same way you enable them on a standalone repository.

About secret scanning alerts for partners

When you make a repository public, or push changes to a public repository, GitHub always scans the code for secrets that match partner patterns. Public packages on the npm registry are also scanned. If secret scanning detects a potential secret, we notify the service provider who issued the secret. The service provider validates the string and then decides whether they should revoke the secret, issue a new secret, or contact you directly. Their action will depend on the associated risks to you or them. For more information, see "Secret scanning patterns."

You cannot change the configuration of secret scanning for partner patterns on public repositories.

About secret scanning alerts for users

Secret scanning alerts for users is available for free on all public repositories that you own.

When you enable secret scanning for a repository, GitHub scans the code for patterns that match secrets used by many service providers. When the scan is completed, GitHub sends an email alert to the enterprise and organization owners, even if no secrets were found. For more information about the repository content that is scanned, see the beginning of this article.

When a supported secret is leaked, GitHub generates a secret scanning alert. GitHub will also periodically run a full git history scan of existing content in public repositories where secret scanning is enabled, and send alert notifications following the secret scanning alert notification settings. For more information, see "About user alerts."

If you're a repository administrator, you can enable secret scanning alerts for users for any public repository. Organization owners can also enable secret scanning alerts for users for all public repositories or for all new public repositories within an organization. For more information, see "Managing security and analysis settings for your repository" and "Managing security and analysis settings for your organization."

You can also define custom secret scanning patterns for a repository, organization, or enterprise. For more information, see "Defining custom patterns for secret scanning" in the GitHub Enterprise Cloud documentation.

GitHub stores detected secrets using symmetric encryption, both in transit and at rest.

Accessing secret scanning alerts

When you enable secret scanning for a repository or push commits to a repository with secret scanning enabled, GitHub scans the contents for secrets that match patterns defined by service providers.

When secret scanning detects a secret, GitHub generates an alert.

  • GitHub sends an email alert to the repository administrators and organization owners. You'll receive an alert if you are watching the repository, if you have enabled notifications either for security alerts or for all the activity on the repository, and if, in your notification settings, you have selected to receive email notifications for the repositories that you are watching.
  • If the person who introduced the secret isn't ignoring the repository, GitHub will also send them an email alert. The email contains a link to the related secret scanning alert. The person who introduced the secret can then view the alert in the repository, and resolve the alert.
  • GitHub displays an alert in the Security tab of the repository.

For more information about viewing and resolving secret scanning alerts, see "Managing alerts from secret scanning."

For more information on how to configure notifications for secret scanning alerts, see "Configuring notifications for secret scanning alerts."

Repository administrators and organization owners can grant users and teams access to secret scanning alerts. For more information, see "Managing security and analysis settings for your repository."

You can also use the REST API to monitor results from secret scanning across your repositories. For more information about API endpoints, see "REST API endpoints for secret scanning."
