Any setting you add manually is locally stored in the computer/device.
I tend to agree!
This is how extensions and apps work either wallet or any platform, all information is locally stored, once you've used another device it will ask again for credintial and information so that it will be able to access from other devices.
Per device it has a different password, as mentioned above, any settings that are stored are locally saved per device used. So it's okay if you will use a different password but it's expected that when you come back to your device it will back to the default.
