Excuse me, what does QQ authentication information mean?

If the verification information is added in this way, 1. If the other party doesn't set specific questions, and the other party knows you, you can let the other party know by writing your name or not, and the other party will add your consent unless he doesn't want to add you. 2. If the other party doesn't know you, doesn't set specific questions and doesn't want to add you, it's useless for you to enter verification information. 3. If the other person doesn't know you and sets specific questions, you can't add him if you don't know the correct verification information. If your question doesn't mean that, then I have no solution.
