Limit what Microsoft Edge syncs to a shared second computer

Signing into Edge can make favorites, passwords, history, extensions, open tabs, payment information and other browser data available across devices. That is helpful on a computer you own, but a shared machine changes the risk. The browser profile and the operating-system account both matter. Review categories before enabling sync, and leave no signed-in profile behind when the borrowed session ends.

Before you start​

Ask whether the computer is genuinely controlled by you. On an employer-managed device, organization policy may set or restrict sync. For a temporary session on another person's computer, using your own device or avoiding account sign-in is usually simpler than trying to sanitize a shared profile afterward.

Do it step by step​

1. Open Edge's profile control and verify which Microsoft, work or school account is signed in. If several profiles exist, select the one you intend to use; a profile picture alone is not proof of the correct account.
2. Open Settings, Profiles, then Sync. Review every offered category before enabling it. Turn off categories you do not want on this computer, especially passwords, payment information, open tabs or history when another person may use the machine.
3. Use a separate operating-system account with a screen lock if you will use the device regularly. A separate Edge profile helps organization, but another person who can open your unlocked OS session may still reach its browser data.
4. Make one harmless test change, such as adding a temporary favorite, and verify only the intended category appears on the second device. Remove the test item afterward. Do not test with a real secret or payment number.
5. Before leaving a borrowed device, turn off sync or sign out of the profile and follow Edge's options for removing local profile data. Close browser windows and check that your account is no longer offered as an unlocked profile.
6. From a device you own, review account devices and security activity if the borrowed machine may have been accessed after you left. Change credentials if you have evidence they were exposed, not simply because the machine was temporarily used.

Check the result​

Only selected data categories sync to the second computer, and the temporary profile is no longer accessible when the session is over. The operating-system account is locked when unattended.

If something goes wrong​

If the Sync page is unavailable, the account type, network or organization policy may control it. Do not infer that sign-out deleted every downloaded file or every local browser item; inspect the chosen sign-out and removal options.

Know the limit​

Stopping sync does not necessarily erase copies already stored on another device. Browser profiles are organization boundaries, not strong isolation from somebody who controls the same OS login. Avoid syncing sensitive categories to devices outside your control. Microsoft Edge sync categories
