Removing someone’s GitHub access does not delete a repository clone already stored on their device. It ends the access granted to their account for future actions on the hosted repository; files already copied locally are separate. For private or confidential code, offboarding therefore needs to address both hosted permissions and retained local data.
What GitHub access controls—and what it does not
GitHub describes a permission as the ability to perform a specific action, while a role groups permissions. These permissions govern what an account can do to resources hosted on GitHub; they do not control files already stored on someone’s computer. GitHub’s repository permission guidance explains collaborator access and retained clones.

As an explanatory analogy—not GitHub terminology—hosted permissions are like a key to a building, while a clone is a set of files already copied onto a separate device. Changing the key does not retrieve those files.
What happens when a collaborator is removed
Removing a collaborator ends the read or write access provided by that grant to the hosted repository. They cannot use that removed permission to fetch new private content or push changes. But a clone they already obtained remains on their device unless it is separately deleted. GitHub explicitly notes that a removed collaborator retains local clones; for private repositories, a fork may be deleted while the local clone remains. Personal repository permissions and organization repository access guidance describe these distinctions.

A local project folder opening successfully proves only that files exist locally. It does not prove the person can contact GitHub for updates or submit changes.
Why a local Git operation can still fail
Commands such as fetch, pull, or push involve a remote connection, so success depends on both authentication and authorization. Authentication establishes which account or credential the client is using; repository permissions determine whether that identity may perform the requested action. A browser session being signed in does not by itself establish that Git on the command line has a working credential or the necessary repository access. GitHub supports different authentication methods across browsers, desktop clients, APIs, and command-line Git. GitHub’s authentication documentation outlines the available methods.
Check the credential method
For HTTPS Git operations, GitHub supports personal access tokens and credential helpers; password-based authentication for Git has been removed. If Git repeatedly prompts for credentials, the credential may be missing, invalid, or not stored by a helper. Follow GitHub’s credential-prompt troubleshooting guidance.
Check the account’s repository permission
A valid credential does not grant repository access by itself. If the account no longer has permission, a remote operation can be denied even though the local repository remains usable for local work. GitHub Desktop’s troubleshooting also distinguishes access problems from SSH public-key configuration issues. See GitHub Desktop authentication troubleshooting.
Check whether the failing repository is a submodule
A project may reference a separate submodule repository. Access to the parent repository does not necessarily grant access to that separate repository. If the main project works but a submodule fails to clone or update, ask its administrator to confirm access to the submodule itself. GitHub Desktop’s troubleshooting guide identifies missing submodule access as a possible cause.

For organization repositories, GitHub says the organization is responsible for ensuring that people who lose access delete confidential information or intellectual property retained locally. Removing hosted access is an important step, but it does not erase existing clones or guarantee deletion of copies in backups or other work environments. Owners should follow their organization’s offboarding and data-handling process and account for approved local copies. The GitHub guidance establishes clone retention; it does not prescribe a complete device-erasure or forensic procedure. Read GitHub’s organization access guidance.
