Does the maintenance engineer verify that the code is safe?

Safe. Like auto insurance, insurance companies want this information in order to determine the information of the insured vehicles. These enterprises will protect users' information, so there is no need to worry that information will reveal these problems, which will be much more convenient after authentication. CAPTCHA is the abbreviation of "automatic public Turing test to distinguish between computer and human", and it is a public * * * automatic program used to distinguish whether the user is a computer or a human.
