Does anyone know or share on securing older devices that no longer receive security updates so they can work a bit longer? In particular I'm wondering about using ChromeOS devices like chromebooks that no longer receive security and other updates to maybe put on developer mode and tweak to make them a bit more secure and possibly still able to be updated to stay a bit functional, ie so old google web store apps might still be able to work, preferred extensions etc and is it still possible to... set them up so if they have problems you can still wipe them (if for instance some people like me might otherwise not be able to fix problems manually) and restore the important bits so it can still keep working hopefully after a wipe?
