Oculus is ending support for its own login system.

The Oculus Blog says that the company is ending support for its own account system. Moving forward, the only way to log into the Oculus services moving forward will be by logging into a Facebook account. This change will apply first starting in October 2020. Those who have not yet activated their Oculus VR devices for the first time will be required to use their Facebook account to log in.

Those of you already with an Oculus account will have two choices. The first is that you can merge your Oculus and Facebook accounts immediately. You can opt instead to wait for a period of about two years. Come January 1, 2023, if you did not merge with a Facebook account the Oculus account will no longer work and you will lose functionality. If you purchased software from Oculus, there is absolutely no guarantee that this software will continue to work after that 2023 cutoff date.

Merging of accounts will not be available until October 2020. Until such a time, you can either have a login with either an Oculus account or a Facebook account. If you bought content on one account but not another, you may not have access to that content on one account until the merge happens.

All new Oculus devices coming out will require this Facebook login.

Facebook says that this change is being done in order to facilitate finding friends in VR as well as providing additional "privacy and safety tools." Those of us with a head on our shoulders should know that Facebook really only cares about gathering more data on your activities and purchases.

Why are you making these changes to accounts on Oculus?

Oculus is owned by Facebook and is one of Facebook’s apps and technologies. Using a Facebook account provides a single way to log into Oculus devices and makes it easier to find, connect and play with friends in VR. It also enables Facebook-powered social experiences, like live streaming gameplay to your Facebook timeline, making calls with parties, joining events, and exploring new experiences like Facebook Horizon. And as Facebook adds new privacy and safety tools, they can be added in VR too.
