Two-tier branch protection: managing who can push in GitHub

Two-tier branch protection: managing who can push in GitHub

While owners and collaborators are the only ones who could push directly, they are often restricted by rules to ensure code quality and security. If you try to push and get an error saying “protected branch,” it means the project requires a PR regardless of your rank.

1. Access Roles (Who has the “Permission”?)

To push anything to a repository, you must first have Write Access.

• Repository Owners: Have full control by default.
• Collaborators: Can push directly if they have been granted “Write” or “Admin” permissions.

2. Branch Protection (Why even Owners/Collaborators might be blocked)

In professional projects, the main or develop branches are usually “protected.” If Branch Protection Rules are active:

• Direct Push is Disabled: Even if you are the owner, GitHub will reject a direct push.
• PR Requirement: You are forced to create a Pull Request, pass automated tests, and often get a peer review before the code can be merged.
