After Tik Tok cashed out in Alipay, Alipay received a red envelope message in the notification bar, but I didn't log in to Alipay. How did I get this message?

This shows that the user used to push the notification does not need you to log in, which means that you have logged in before, and although you quit, there is still your Alipay information in your mobile phone. When pushing messages, the id you use does not require you to log in. You can look at the homepage of Taobao, which can show the quantity to be collected, but when you want to see the details, you will be prompted to log in. The principle is actually the same.
