Answer Key

Securely accessing multiple systems and accounts

Section A: Quick Questions

B — A unique passphrase for each account

A — Log out before you leave

A — List all your accounts and check which ones share a passphrase

A — Turn on multi-factor authentication as well as a unique passphrase

B — Install software updates when they are available

Section B: Match the Pairs

unique passphrase per account → Gives every account its own long phrase so one stolen password cannot unlock your other accounts

log out on shared devices → Ends your session so the next person using the computer cannot open your accounts

Audit your accounts: list every account and check which ones have a weak or re-used password → account_audit = [email, games, school, music]

Combine habits: use a unique passphrase, log out when done, and keep software updated → passphrase + logout + updates = secure access

school_pass = game_pass = email_pass = "sunny123" → The same short password is re-used for every account, so one leak unlocks them all. Each account needs its own unique passphrase.

use library computer -> check email -> close the browser tab → Closing the tab does not log you out, so the next person may still reach your email. You should log out before leaving a shared device.

Section C: Definitions

secure access — Using a unique passphrase for each account, plus safe habits like logging out on shared devices and keeping software updated, to protect all your systems and accounts.

Section D: Fill in the Blanks

CHECK each account has a unique passphrase

IF device is shared THEN logout when done

FOR EACH account IN accounts: audit it

IF an update is waiting THEN install it

secure = passphrases + logout + updates

Section E: Spot the Error

D — The comma between the arguments is missing. It should be save(a, phrase) so each account's unique passphrase is saved.

C — An if statement needs a colon at the end. It should be if shared and done: so logout() runs when you finish on a shared device.

C — There is no comma between the text and the variable. It should be print("Update", item) to show each item that needs updating.

A — The list is missing its closing square bracket. It should end with ] so the account audit list is complete.

D — The closing quotation mark is missing, so the string is never finished. It should be print("Strong enough").
