Answer Key

Unique passphrase for each account

Section A: Quick Questions

A — Use a different passphrase for each account

A — Change that account's passphrase straight away

A — If one account is breached, criminals can try it on the other account

B — Your main email account, because it can reset other accounts

B — Pick a different set of random words for each account and picture a silly story for each one

Section B: Match the Pairs

email_account = "purple-turtle-sings-loud" bank_account = "seven-tiny-boats-wave" → Each account has its own different passphrase, so one leak does not open the others

all_accounts = "purple-turtle-sings-loud" → One passphrase is reused for every account, which is risky if it is leaked

Rank accounts by importance so the most important ones, like email and banking, get the strongest unique passphrases → importance = ["bank", "email", "game"]

After a breach, change the leaked passphrase straight away to a new, different one → game_pass = "blue-koala-jumps-high"

school_pass = "cat-hat-sun-map" shop_pass = "cat-hat-sun-map" → Two accounts use the same passphrase. Give each account its own different passphrase.

game_pass = "leaked-pass-1" # breach happened, keep using it → The passphrase was leaked in a breach but not changed. It should be changed straight away to a new unique one.

Section C: Definitions

unique passphrase — A different passphrase for every account, so if one is leaked in a breach, criminals cannot use it to get into your other accounts. Change it straight away after a breach.

Section D: Fill in the Blanks

IF emailPass == bankPass THEN
    SAY "Change one passphrase"
END IF

SORT accounts BY importance
SAY accounts[1]

IF breach = TRUE THEN
    changePassphrase(account)
END IF

FOR EACH account IN accounts
    createPassphrase(account)
END FOR

passphrase = JOIN(word1, word2, word3)
SAY passphrase

Section E: Spot the Error

C — The game account reuses the bank passphrase. Each account needs its own unique passphrase, so it should be game = "tall-owl-eat-sand".

B — A for loop line must end with a colon. It should be for a in accounts: so every account gets a new passphrase.

D — == compares values and does not store the importance score. Use = to assign the score: scores["game"] = 1.

C — Both accounts now get the same passphrase because they use the same word list. The email passphrase should be built from list a.

A — Python's Boolean value is True with a capital T. Lowercase true is not defined, so it should be breach = True.
