How long will the general QQ verification code disappear? My system has also been reinstalled!

If you have time, that's it. It will take some time. Under normal circumstances, you will not be required to verify your identity if you often log in your QQ number in a city. Only when you suddenly log in from a different place will you be asked to verify your identity. This is to prevent QQ from being stolen. My previous QQ number often logged in from different places. News tips, when you check my QQ coins in the province or abroad, as long as you often use your QQ number in a city, you won't always be asked to verify it.
