Final answer:

Kelly should change her password because it could be easily guessed, it isn't unique, and passwords should be changed regularly. Stronger passwords enhance security and protect online accounts more effectively. Using complex and different passwords for each account is essential for safety online.


Explanation:

Importance of Strong Passwords


Kelly should change her password from "P4ssword" for several important reasons:



  1. It could be easily guessed. Despite the inclusion of a number, the password is still based on a common word, making it vulnerable to dictionary attacks. Hackers use tools that can quickly guess passwords that are based on simple substitutions.

  2. Passwords must be unique. Ideally, each password should be different for each account to prevent a security breach on one account from compromising others. If a hacker gains access using the same password across multiple accounts, they can take over all of them.

  3. Passwords should be changed regularly. It's a good practice to update passwords periodically to enhance security. This reduces the risk if a password has been exposed without the user's knowledge.


Therefore, Kelly should consider creating a more complex password that includes a mix of letters, numbers, and special characters, and is not based on easily guessable words.
