Why did I receive the pinecone travel verification code for no reason?

1. Mobile phone information leaked. The mobile phone number that receives the short message is generally the mobile phone number that is bound to the identity when registering. Under normal circumstances, personal information should be protected and not leaked at will to prevent property losses. 2. It is possible that someone else entered the wrong number, causing the verification code to be sent to their mobile phone. 3. The mobile phone may be infected with a virus, and others can directly obtain those verification codes.

Mobile phone verification code is the most effective verification code system by sending verification code to mobile phone. Large websites, especially shopping websites, provide SMS verification code function, which can accurately and safely ensure the safety of shopping and verify the correctness of users. Some authentication code providers provide SMS authentication code service. Each website sends a request to the provider's server through the interface, and the server sends random numbers or letters to the mobile phone, and the provider's server verifies the authentication code uniformly.
