I have seen posts as far back as 2016 of Oculus Rift owners asking OCULUS for parental controls. Here it is 2019 and we also have Oculus Go (and Oculus Quest will be released shortly) and OCULUS continues to ignore this request from it's customers. It is not hard to add two-factor authentication when someone is trying to access the web browser in Oculus. Or just like Android apps where you can install an app that will hide apps or require a pattern or pin in order to access the web or apps you specify.
And it's not just about hiding or keeping children from accessing inappropriate content on the web in Oculus Go, this applies to ADULT friends and family as well!
I'm still trying to figure out why Oculus refuses to add any of these requested features? It makes no sense to me. Especially since your customers help sell your headsets by allowing people we know access to OUR headsets to demo them, therefore increasing your sales by more consumers buying your products who normally wouldn't!
