Answer Key

Weak passwords

Section A: Quick Questions

A — True

A — Tr7$mQ9!zL

B — False

A — Long random password

B — False

Section B: Match the Pairs

password = "123456" → An example of a weak, easily guessable password

password = "qwerty" → A common weak password based on a keyboard pattern

A strong password uses length, randomness and mixed characters → password = generate_secure()

Enforcing a minimum password length improves security → min_length = 12

password = username → The mistake: setting the password equal to the username

password = birthdate → The mistake: using a predictable personal detail as the password

Section C: Definitions

Weak password — A password that is short, common, or predictable, making it easy for attackers to guess or crack.

Section D: Fill in the Blanks

password = "123456"

min_length = 8

if len(password) < min_length:

def check_strength():

is_weak = True

Section E: Spot the Error

A — Line 1 uses the word "password" itself, one of the most common weak passwords.

B — Line 2 sets the minimum required length to 4, far too short to be secure.

C — Line 3 overwrites the secure password with the common, predictable "qwerty".

D — Line 4 sets the password equal to the username, making it trivially guessable.

E — Line 5 skips the complexity check, undoing the earlier security requirements.
