Hello ,
Thank you for posting in Microsoft Community forum.
To manage the issue of two computers sharing Wi-Fi passwords under the same Microsoft account, and ensure that each computer is only connected to the designated guest network, you can consider the following methods:
- On each computer, manually forget the Wi-Fi network you don't want to connect to. This prevents your computer from automatically connecting to the wrong network.
- In the Wi-Fi settings, make sure to turn off the "Auto-connect" option. This prevents the computer from automatically connecting to other networks when the signal is strong.
- If possible, consider using a different Microsoft account for each PC. This allows them to be completely isolated from their network settings and passwords.
- If you do not want to sync Wi-Fi passwords between different devices, you can turn off Wi-Fi password syncing in the settings of your Microsoft account.
- If you have permission, consider reconfiguring the settings of the guest network to ensure that its SSID and password are not easy to connect to by mistake.
- Try setting up MAC address filtering in your router to allow only specific devices to connect to the network.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
