A leaked personal access token shouldn't expose every project its owner can reach. Fine-grained PATs scope each token’s permissions to the job. (opens in new tab)

Fine-grained personal access tokens (PATs) reduce credential exposure by limiting each token to only the projects, groups, resources, and actions required for a specific task. GitLab’s beta lets users replace broad api or read_api tokens with narrowly scoped permissions, reducing the impact of leaks. The feature is not yet recommended for production because coverage is still incomplete.

Why Narrow PAT Privileges

  • Broad, user-scoped tokens can access every project the user can reach.
  • A leaked token might expose source code, pipelines, container images, or CI/CD variables across many projects.
  • Fine-grained tokens limit both access and potential remediation to the affected project or resource.
  • They complement lifetime limits and automatic revocation.

How Fine-Grained Tokens Work

  • Scope access by location:
    • Personal projects
    • All projects and groups where the user is a member
    • Specifically selected projects and groups
  • Assign independent Create, Read, Update, and Delete permissions.
  • Supported resources include Issues, Merge Requests, Pipelines, Repositories, and Container Registry.
  • Example: a container-publishing pipeline can receive Create and Read access only to one project’s registry.

Auditing and Beta Coverage

  • The token management table displays scopes and per-resource permissions for all tokens.
  • This makes over-privileged credentials easier to identify during reviews.
  • Fine-grained PATs currently support about 75% of REST API endpoints.
  • GitLab plans to add remaining REST endpoints and expand GraphQL support.
  • Existing traditional PATs continue working alongside fine-grained tokens during the beta.

Getting Started

  • Go to User Settings → Personal Access Tokens.
  • Select Fine-grained token when generating a token.
  • Choose the permitted projects or groups and assign resource permissions.
  • GitLab recommends avoiding fine-grained PATs in production until general availability.

Teams should begin evaluating fine-grained tokens for automation and adopt one token per job, with the smallest practical scope. Feedback during the beta will help shape broader endpoint coverage and future improvements.
