# How to: Revoke a machine's access

1. Open the project menu (the project name at the bottom of the sidebar) and
   choose **Share**.
2. Under **Machines with access**, find the machine.
3. Click **Revoke** — or **Revoke write access** to keep it reading but stop
   it sending changes back.

This stops future copies to that machine. Anything it already copied stays
on it — revoking doesn't reach back and delete what it already has.
