### GitLab Token Expiration Time and Management

In the context of managing access within GitLab, tokens play an essential role in authenticating users or services that interact with GitLab resources. However, specific details about setting up artifact expiration are provided for a different aspect of GitLab's functionality[^1]. For personal access tokens (PATs), which are often what is meant by "GitLab tokens," there isn't a direct configuration option like `expire_in` used for artifacts.

For PATs created through GitLab’s interface:

- When creating a new Personal Access Token via the User Settings -> Access Tokens section, one must specify its expiry date during creation.
- The minimum lifespan allowed for these tokens is typically short-term, while longer durations depend on administrative settings but generally do not exceed several months without explicit approval from administrators.

To manage existing tokens' lifespans:

- Once issued, modifying the expiration directly is unsupported; instead, revoking old ones and issuing fresh tokens becomes necessary when adjustments need making regarding their validity period.

Regarding CI/CD pipeline variables or deploy tokens specifically configured inside projects:

- These might have distinct rules concerning duration depending upon version updates introduced periodically by GitLab developers.

# Example command to create a project-level deploy token with custom expiration using API
curl --request POST \
  --url 'https://gitlab.example.com/api/v4/projects/<project_id>/deploy_tokens' \
  --header 'PRIVATE-TOKEN: <your_access_token>' \
  --form name='my_deploy_token' \
  --form expires_at='2023-12-31'
