How to remove a collaborator from a GitHub repo?

 

Step 1: Navigate to GitHub and sign in

 

• Open your web browser and go to https://github.com.
• Click Sign in (top right) and enter your GitHub username/email and password.
• After signing in, confirm you see your avatar in the top-right corner.

 

Step 2: Open your repository

 

• Click your avatar (top right) and select Your repositories.
• From the list, click the repository from which you want to remove a collaborator.
• You should now be on the main page of that repository.

 

Step 3: Go to the repository Settings

 

• On the repository page, locate the tab bar near the top.
• Click the Settings tab (usually the last tab).

 

Step 4: Access the Manage access section

 

• In the left sidebar, click Manage access.
• GitHub may prompt you to re-authenticate for security. Click Confirm password or complete the authentication flow.

 

Step 5: Find the collaborator you want to remove

 

• Under Manage access, you’ll see a list of users and teams with access to this repository.
• Scroll through or use the search field to locate the collaborator’s username.

 

Step 6: Remove the collaborator via the web interface

 

• Next to the collaborator’s name, click the gear icon (⚙️).
• In the dropdown, click Remove access.

 

Step 7: Confirm the removal

 

• A confirmation dialog appears: “Remove this collaborator from the repository?”
• Click the Remove from repository button to confirm.

 

Step 8: Verify that the collaborator has been removed

 

• After confirmation, you should no longer see the user listed under Manage access.
• The removed collaborator will lose access immediately and receive a notification email.

 

Step 9: (Optional) Remove a collaborator using GitHub CLI

 

• Ensure you have the GitHub CLI installed and are authenticated (gh auth login).
• Run the following command, replacing OWNER/REPO and USERNAME:

gh repo remove-collaborator OWNER/REPO USERNAME

• If prompted, confirm the operation by typing Y and pressing Enter.

 

Step 10: Final confirmation

 

• Return to the repository’s Manage access page (web UI) to ensure the collaborator is gone.
• Your repository’s access list now reflects only the remaining collaborators and teams.
