What does it mean to add QQ friends to input verification information?

Authentication information is a friend authentication function, which includes the following aspects: If you don't want to be friends of others casually and don't want strangers to talk to you, then choose authentication function and establish personalized authentication function.

Qq verification message plus friends means that you sent a verification message before but didn't agree, so you added friends again through the verification message. When you add a friend in this way, the source of the other party's message will be displayed as a verification message. The other party may also see your message or comment in other people's space and add it through your avatar information.

Hello! This is because the other party has set up authentication. There are two authentication methods: ① I need identity authentication to be listed as a friend. Check this box, and when the other party requests to be friends, enter the verification code to send the message of adding friends; I need to answer my questions correctly to be listed as a friend.

So the displayed content comes from the verification message. If the message source of the new friend received in QQ is a verification message, it means that the other friend was added before, but the other party did not agree. It is the reply message in the verification message that initiated the dialogue, so there will be such a prompt.
