You need to look through the routers config options on its www page to find out if this is possible, some routers can do it, some cant.
however, if sombody has physical access to your router, they can still reset it to defaults, so if your worried about security vs a user with physical access, unless the router uses authentication info that would be cleared by it being reset, and only you know that info, your wasting your time by trying it (unless its to stop a really dumb kid with no smart friends)`
