I didn't log in, but I received the verification code.

The reasons for not logging in and receiving the verification code are: network delay, advertisement, others' operation error, stolen app account, suspected fraud or others.

1. app was used to receive the verification code before, but the verification code came late because of the busy network or bad signal.

2. A way for an app or website to advertise: For example, an app writes the name of the app in the text of the verification code, which is particularly easy to attract people's attention, so that you can pick up your mobile phone and have a look, thus achieving the advertising effect.

3. Some people make mistakes: when registering or logging in some software, you need to fill in the mobile phone number and accept the verification code. It may be because of an input error, the wrong phone number was entered, and the wrong phone number happened to be your own number, which led to the verification code being sent to you.

4. The 4.app account is stolen: after the account is stolen, others will change the binding mobile phone number, and generally such an operation will send a verification code to the old mobile phone number.

5. Suspected fraud: For example, fraud criminals pretend to be financial institutions such as banks and use verification codes as the first step to open fraud crimes.

6. Other reasons: There are many other reasons for receiving the inexplicable verification code. In short, no matter what the reason, after receiving the verification code, carefully browse the characters in the verification code information, carefully recall the operation of the mobile phone in these two days, and improve the awareness of information security protection and financial asset fraud prevention.
