Websites such as Facebook, LinkedIn (LinkedIn) or Twitter will require users to register, fill in information, set transaction passwords, query passwords, and so on. However, the registration procedures are cumbersome, and at the same time, the control of user data is lost, because some private information is left in the information database of the website, which may
be stolen by "illegals" with ulterior motives. In addition to dissatisfaction and anger, there is no effective means.
If a website like Facebook is willing to accept user information provided by a third-party website for registration and login, then users will be happy to use a third-party website to manage personal information, especially if this third-party website uses a decentralized distributed identity authentication system.
