Passwords protect user accounts and systems by ensuring only authorised users can log in. Strong passwords are long, complex, and difficult to guess, making brute-force attacks much harder.
Key points
Definition:Password: a secret string of characters used to verify a user's identity and protect access to accounts and systems.
Strong passwords should be: long, contain a MIX of uppercase, lowercase, numbers, and symbols, and be HARD TO GUESS.
Help prevent: brute-force attacks, unauthorised access to accounts.
Passwords should be changed regularly and not reused across multiple accounts.
Exam Tip:If asked how to make passwords more secure, mention: LENGTH, COMPLEXITY (mix of character types), avoiding dictionary words, and not reusing passwords.
