Windows users may want to try the built-in Bluetooth proximity locking feature: Lock your Windows 10 PC automatically when you step away from it https://support.microsoft.com/en-us/help/4028111/windows-lock-your-windows-10-pc-automatically-when-you-step-away-from https://support.microsoft.com/en-us/help/4028111/windows-loc... While macOS doesn't include such a feature out of the box, apps like Near Lock https://nearlock.me https://nearlock.me exist. EDIT: Just found Rohos Logon Key for Windows and macOS: https://www.rohos.com/products/rohos-logon-key-for-mac/ https://www.rohos.com/products/rohos-logon-key-for-mac/ It "converts any USB drive into a security token for your computer" and can "automatically lock your Mac screen when the key is unplugged".
