What does 360 verification code mean?

It is a protective measure taken by 360 to ensure the security of user accounts.

360 SMS check code is a protective measure taken by 360 to ensure the security of user accounts. Generally, users are required to choose the binding method of mobile phones. When your account is stolen and you want to change your password, you have to confirm it through your bound mobile phone. If you do it yourself, you can enter the check code in your mobile phone at any time. If you don't operate it yourself, others won't know your bound mobile phone, and you can't get the check code sent by 360. Once you find that this check code is not your own operation, I suggest you change your password immediately so that people who have stolen it cannot log in.
