Random password generation

Password is a technique for confusion, which hopes to transform normal (identifiable) information into unrecognized information. Of course, for a small number of people, such unrecognized information can be reprocessed and recovered. Password is the general name of "password" in Chinese. In fact, the "password" entered when logging on the website, e-mail and bank withdrawal should only be called "password" strictly, because it is not an original "encryption code", but can also be called a secret number.
