Anti-theft tips for QQ

I believe many people have experienced their QQ passwords being stolen, and the significant losses caused by the loss of important data on QQ. Many people are terrified when they talk about it. I've also seen many people online write about some theft prevention measures, such as setting passwords with many characters and adding symbols. Actually, all these are useless. So, how can we effectively prevent QQ passwords from being stolen? Since I have time today, I would like to exchange ideas with everyone on this topic.
