Password Security: Creating Strong and Unique Passwords

Learning Objectives Define the characteristics of a strong password, including length, complexity, and unpredictability. Explain why using unique passwords for different accounts is critical to prevent credential stuffing attacks. Differentiate between weak, medium, and strong passwords by analyzing specific examples. Create a memorable and strong password using the passphrase method. Identify at least three common password creation mistakes, such as using personal information or keyboard patterns. Explain the basic concepts of brute-force and dictionary attacks in the context of password cracking. Describe the role of a password manager and two-factor authentication in a personal security strategy. Ever used your pet's name or your birthday as a password? 🤫 Let&#039...

TermDefinitionExample Password StrengthA measure of a password's effectiveness against guessing or brute-force attacks. It is primarily determined by its length, followed by its complexity (use of uppercase, lowercase, numbers, and symbols) and unpredictability.The password `Tr0ub4dor&3` is strong, while `password123` is extremely weak. Brute-Force AttackA cyberattack where a program systematically tries every possible combination of characters, one by one, until it guesses the correct password. Longer and more complex passwords make this take an impossibly long time.A hacker's software trying 'a', 'b', 'c', ... 'aa', 'ab', 'ac', etc., to log into your account. Dictionary AttackA more targeted type of brute-force at...

The Length-Over-Complexity Rule length > complexity A longer password is exponentially harder to crack than a short, complex one. Always aim for a password that is at least 15 characters long. A short password like `P@5s` can be cracked in seconds, while a long one like `MyFirstDogWasAGoldenRetriever` would take centuries with current technology. The Uniqueness Rule 1 Account = 1 Unique Password Never reuse passwords across different websites. If one site is breached and your password is stolen, attackers will use automated programs to try that same email and password combination on hundreds of other popular sites (this is called 'credential stuffing'). The Passphrase Method Combine 4+ random, unrelated words. Create a strong and memorable password by st...
