What is the health cloud verification code?

Health cloud verification code is an effective verification code system by sending verification codes to mobile phones.

Not only Health Cloud, but also 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.
