You can use this system to hide certain locations, gimmicks, etc. in your world, and without worried about leaking of the passcodes (unless you give the QR Code to someone untrusted). When users want to open this lock, they will have to use an authenticator app such as Google Authenticator. It is very easy to setup. Prepare your VRChat SDK3 world project with UdonSharp, import and drag the prefab to the scene, click "Generate" for unique secret, use your favorite authenticator app to scan the QR code (or save it as an image file to let others can scan it too), add the objects you want to turn on/off or let user teleport to to the Basic Unlock Handler attached. In the package I have also include a whitelist/blacklist system that optionally integrate with this passcode lock, which can let users temporary add themselves for gimmicks that exclusive available to certain users. This system is extensible, as it have provide custom callback events that you can use Udon/U# to integrate with it. You can have a look on how Basic Unlock Handler is implemented to get started.
