On August 24, the social networking giant meta officially launched its so-called meta account and meta horizon profile on Tuesday, local time in the United States. They will be used to replace the personal social media accounts used to log in to the company's virtual reality (VR) system, namely Facebook and instagram accounts. New and old users of meta VR devices need to register a meta account to log in and access metaverse. Meta is abandoning the old-fashioned login method after complaints about privacy issues arising from the use of personal social media accounts. However, meta said that it still allows users to create meta accounts using Facebook and instagram accounts. If someone chooses to create a meta account through their social media account, they will connect in the "account center", which is the central hub of the entire meta connection experience. Although meta encourages users to connect through a meta account, those who log in using oculus will be allowed to continue to log in this way until January 1, 2023. As consumers switch their login methods, meta claims that people will "still be able to access all VR content previously purchased and downloaded." Although there is no need to connect to the social media account operated by meta, the company still regards it as an option. Meta claims that this connection will allow users to get a better experience in VR, such as sharing live streams, sending messages and finding followers more quickly. To start creating a meta account, users must install the latest software on oculus app and VR helmet. In addition to the meta account, the "meta horizon profile" will also replace the oculus account that has been used. These profiles will become the basis of all virtual avatars and will be regarded as social information in the metauniverse. The company once used the word "friends" in the metauniverse, but now regards them as "fans", which makes the horizon world platform feel like an instagram. Protecting personal privacy is still a very urgent issue for twitter. The meta account will provide users with three options, namely "open to all", "friends and family" and "single person". All these options have different effects on who can connect and view personal accounts. If users choose to skip privacy settings, they will be opened to "friends and family" by default. Users can also choose to set their meta horizon profile as private, which requires users to accept attention requests. By default, the accounts of minors aged 13 to 17 will be set as private accounts. At present, these accounts are only linked to VR related login accounts, but this does not mean that meta does not
