The correct answer is: A. Code word
A code word is a word or phrase that is used to represent something else. In the context of the question, a code word is used to represent a password. This is done so that the password is not easily blocked by hackers.
A code word can be any word or phrase that is not easily guessed. It is important to choose a code word that is not related to the password itself. For example, if the password is “123456”, a good code word might be “cat”.
Code words can be used to protect passwords in a number of ways. One way is to use a code word to encrypt the password. This means that the password is converted into a form that cannot be read by anyone who does not know the code word. Another way to use a code word is to store the password in a safe place, such as a password manager.
Code words are a simple but effective way to protect passwords. They are easy to use and can be very effective at preventing unauthorized access to accounts.
