Git Repository Permission Management: How to Set Access Permissions for Team Members

Git repository permission management serves as the "access control system" for team collaboration, with the core goal of ensuring code security and preventing unauthorized modifications or leaks, while adhering to the principle of least privilege (allocating only the necessary permissions). Common permission categories include: Read (read-only access, suitable for new team members or documentation authors), Write (ability to commit code, for regular developers), and Admin (highest privileges, for project leads). Taking GitHub as an example, the setup steps are as follows: Navigate to the repository → Settings → Manage access → Add collaborator to assign permissions (select Write for regular members, Read for those needing only access, and Admin for project leads). For advanced management, branch protection rules can be configured (e.g., requiring PR reviews and CI tests before merging). Guidelines: Avoid overuse of high-privilege accounts, regularly revoke access for departing members, and use team groups for batch permission management. The core principle is to clarify responsibilities, apply the least privilege, and enforce branch protection, ensuring permissions are "just sufficient."
