Oculess is a new program that lets you use your Quest 2 without a Facebook or Oculus account
When Facebook suffered massive outages earlier this week, it rendered anyone with an Oculus Quest headset unable to play any of their games, as connection to Facebook is mandatory. Enter Oculess, a new sideloadable tool that lets you unlink your headset from your Facebook or Oculus accounts and still use it. In order to sideload anything on the device, you'll need to access Developer Mode, which can be done by giving a phone number or payment details (you won't be charged) to Facebook for verification.
Unlinking the accounts has the side effect of preventing the use of official Oculus apps, such as the Oculus Store or Browser, but the creator of Oculess has created a handy list of alternatives you can use to replace the disabled features. Most importantly, however, is that the hand tracking isn't affected by the removal of Facebook accounts, so games should still run just fine.
