Question

When creating passwords for secure accounts, which of the following rules should you apply?
a.
use personal information that is easy to remember
b.
use a variety of letters, numbers and characters
c.
use a sequence or pattern of numbers
d.
use the same password for all accounts

Answer 1

Correct answer: b.

Explanation:
- b (use a variety of letters, numbers and characters) is good — helps make passwords harder to guess or brute-force.
- a, c, and d are poor practices:
- a: personal info (names, birthdays, pets) is easy for attackers to find and guess.
- c: sequences/patterns (1234, qwerty) are predictable.
- d: reusing the same password across accounts means one breach compromises many accounts.

Quick tips: use long passphrases or randomly generated passwords (12–16+ characters), a mix of upper/lowercase, numbers and symbols, enable multi-factor authentication, and store passwords in a reputable password manager.
