Understanding Password manager in Years 5–6 Digital Systems

What it does: The vault holds many passwords, but only one strong master passphrase is needed to open it. A trusted adult can help you set up the tool safely and decide whether it is safe to save a password on that device. A password manager keeps many passwords safe in one place and fills them in for you, so you don't have to remember each one. Browser-saved passwords on a shared device could be used by the next person. Don't save them there and always log out. A long passphrase made of several random words is much harder to guess than a short, simple one like abc123.

Common mistakes: A single = stores a value instead of comparing. The password manager should check the typed master passphrase with ==, so the line should be: if enter == master:. The = is missing, so the password is never saved in the vault. It should be: vault["email"] = "Tr33!lamp".

Quick Questions

1. What does a password manager do?
A. Deletes your passwords after each login
B. Stores and fills in many passwords for you ✓
A password manager keeps many passwords safe in one place and fills them in for you, so you don't have to remember each one.
2. How is a password manager protected?
A. By one strong master passphrase ✓
B. By a different short word for every password
One strong master passphrase locks the whole password manager, so it is the key to everything inside it.
3. Who should know your master passphrase?
A. Only you (and a trusted adult who helps you) ✓
B. Your friends, so they can help you log in
The master passphrase must stay private. Only share it with a trusted adult, never with friends or online.
4. Your browser asks, 'Save this password?' on a shared school computer. What should you do?
A. Choose 'Save' so the next person can log in fast
B. Choose 'Never' and log out when finished ✓
Browser-saved passwords on a shared device could be used by the next person. Don't save them there and always log out.
5. Which is true about browser-saved passwords?
A. They are a simple password manager built into the browser ✓
B. They are safe to use without any device lock or passphrase
Browsers can save and fill in passwords, but the device or browser still needs to be protected with a strong lock or passphrase.

Match the Pairs

master passphrase → The one strong phrase that unlocks a password manager, so you only have to remember this one
browser-saved password → A password that a web browser remembers and fills in for you on a website you have logged in to
A password manager stores many passwords behind one master passphrase that only you know → Vault: 40 passwords | Unlock with: purple-koala-sings-loudly
Ask a trusted adult for help when setting up a password manager or saving a password in a browser → Browser asks: Save password? -> Ask a trusted adult first
Master passphrase: 1234 → The master passphrase is weak and easy to guess. It should be a long, strong passphrase, because it protects every password in the manager.
Save password in browser on a shared school computer? Yes → Saving passwords in a browser on a shared device lets other people log in as you. Do not save them there, and ask a trusted adult if unsure.

Spot the Error

Question 1
A master = "blue tiger lamp"
B enter = input("Master: ")
C if enter = master:
D show(vault)
Line C — A single = stores a value instead of comparing. The password manager should check the typed master passphrase with ==, so the line should be: if enter == master:
Question 2
A vault = {}
B vault["email"] "Tr33!lamp"
C vault["game"] = "Zk9#river"
D print(len(vault))
Line B — The = is missing, so the password is never saved in the vault. It should be: vault["email"] = "Tr33!lamp"
Question 3
A vault = load(master)
B sites = ["mail", "game"]
C for site in sites:
D fill(master)
Line D — The manager fills in each site's own saved password from the vault. The master passphrase only unlocks the vault and is never typed into sites. It should be: fill(vault[site])
Question 4
A need_help = True
B if need_help
C ask(trusted_adult)
D setup(manager)
Line B — The if line is missing its colon at the end. It should be: if need_help:
Question 5
A site = "school.com"
B pw = "Mo0n&frog"
C if user_says("Save?"):
D browser.save(site)
Line D — A browser-saved password needs both the site and the password. The pw is missing, so it should be: browser.save(site, pw)
