I got up early in the morning and took two verification codes from my mobile phone. What happened? I haven't played this Miha Tour before, and I don't even have this thing.

Generally speaking, this is because your mobile phone number was leaked, known by others and bombed by SMS. ?

I suggest you add SMS interception first, or download a firewall software with a white list, and set a white list so that strange SMS can't be sent to your mobile phone. ?

Some people will be asked to enter the verification code when using some apps, and sometimes they will enter the wrong number when filling in the mobile phone number. Click send verification code and it will be sent to you. The other party's mobile phone number is only one number away.

There is a risk of theft. Sometimes you receive this kind of short message, maybe some users know your user name, but they don't know your password. They may know the password habits you used and try to crack them. Although the probability of this kind of cracking is low, many people will try.

The verification code is a public automatic program, which is used to distinguish whether the user is a computer or a person. Verification code is widely used in many websites, which can not only prevent malicious password cracking, ticket brushing and forum flooding, but also effectively prevent a hacker from constantly trying to log in to a specific registered user by using a specific program brute force cracking method.
