Can WeChat find personal information without real-name authentication?

Ordinary people can't, but public security organs can. Ordinary people can't use micro-signals to find personal information normally, and it is even more impossible to find it without real-name authentication. Although the other party is already your good friend, you can only see the last 1 word of the name when transferring money. So I can't find personal information. Because the micro-signal must be bound to the mobile phone number, and the mobile phone number information is often involved in the use of WeChat, the platform will carry out privacy protection. Only the public security organs can take necessary technical investigation measures against the fugitive criminal suspects and defendants who are wanted or approved or decided to arrest.
