What is the confidentiality of WeChat?

To view other people's WeChat chat records, you can only log in to his WeChat. And even if you know his WeChat password, it is not easy to log in to his WeChat. Because posting his WeChat on your mobile phone needs verification, you have to choose a few photos of his friends from a pile of photos, and there are only three chances. If his mobile phone number is bound to WeChat, WeChat will send a text message to tell him that someone is trying to log in to his WeChat. Wechat is much more confidential than qq and does not support simultaneous online.
