Why does my mobile phone receive the message 10086 (your random password: xxxxx)?

Hello, at present, the staff of Beijing Mobile will not get the random code for you without your permission, or call you for no reason. If you don't need to get a random code when handling any business, I suggest you don't tell others the random code you received inexplicably, in case the other party uses your mobile phone number to do something you don't know. Please refer to.
