Password Passport is a free printable computing worksheet for Year 4 (ages 8 to 9). Children earn a stamp for each password rule, then use the rules to crack weak passwords and suggest better ones. It needs only paper and a pencil. Page 2 gives the grown-up notes, help, a stretch idea and the answers.
It comes from the Mini Minds Hub, the free library of printables from Jaques of London, the British games and toy company that has been making games for families since 1795. Print both pages, give page 1 to your child and keep page 2 for yourself. Black and white printing works well.
What is on the sheet
Children start with four stamp rules: LONG, MIX, SYMBOL and PRIVATE. There are cards to cut out and use, and a table to fill in. They turn a silly sentence into first letters, then add numbers, symbols and extra letters to build their own strong password. Then they look at a weak password, note which stamps it fails and write a better idea.
- Stamp 1: LONG. Use 12 or more characters.
- Stamp 2: MIX. Use capital letters, small letters and numbers.
- Stamp 3: SYMBOL. Add one symbol, like ! or # or ?
- Stamp 4: PRIVATE. No name, age, pet or school.
- Silly sentence
- First letters
- My strong password
- Weak password
- Stamps it fails
- A better idea
Worked example: from sentence to password
Build a password from the sentence: Two purple frogs jump over the big silver moon.
This is our own example. It uses a different sentence from the sheet, so children still work out their own. It shows two ways to check the work.
Method 1: build it in stages- Write the first letter of each word: T, p, f, j, o, t, b, s, m. That makes Tpfjotbsm, which is 9 characters.
- Add two numbers on the end: 64. Now there are 11 characters.
- Add one symbol: !. Now there are 12 characters.
- LONG: count the characters in Tpfjotbsm64!. There are 12, so it earns the stamp.
- MIX: it has a capital T, small letters and the numbers 6 and 4, so it earns the stamp.
- SYMBOL: it has a !, so it earns the stamp. PRIVATE: it has no name, age, pet or school, so it earns the stamp.
How to build a strong password
Start with a silly sentence
Make up a sentence that is odd and easy to picture. Silly sentences are easier to remember than a list of random letters.
Take the first letters
Say the sentence aloud and write the first letter of every word. Pointing at each word helps children keep their place.
Add numbers, a symbol and extra letters
Put a few numbers and one symbol such as ! or # or ? into the password. Keep adding until you reach 12 characters or more.
Check the four stamps
Read the password back against LONG, MIX, SYMBOL and PRIVATE. If one stamp is missing, change the password until it earns them all.
Why do passwords matter?
A password is a secret that proves an account belongs to you. It keeps your games, messages, photos and school work away from people who should not see them. Children are starting to use more devices and accounts, so Year 4 is a good time to talk about what makes a password hard for someone else to guess.
Weak passwords are usually short, made of one kind of character, or built from details that people who know you could guess, such as a name or a pet. Strong passwords are longer, mix different kinds of characters and keep personal details out. A silly sentence gives children a way to make one that they can still remember.
Use pretend passwords only. Children should never write a real password for any account on the sheet, and should never share a real password with friends. A trusted adult can help with real accounts.
Password facts
- A password is a secret. It is only a good secret if other people cannot guess it.
- Longer passwords are harder to guess than short ones.
- Computers can try a very large number of guesses very quickly.
- Using a different password for each account is safer than using one password everywhere.
- A password made from a silly sentence can be easier to remember than a random jumble.

Ideas to talk about together
- Why a secret needs careA password only works while it stays secret. Ask your child who they would tell, and why a trusted adult is the right person.
- What people can guessPeople who know us can often guess things about us. Talk about which details are easy for others to find out.
- Why length helpsEach extra character gives a guesser more to work out. Ask your child why a longer password might be harder to crack.
- Why memorable mattersA strong password is no use if you forget it. Talk about how a silly picture in your head helps you remember.
Key words
- PasswordA secret set of characters that lets you into an account.
- CharacterOne letter, number or symbol. Each one counts towards the length.
- SymbolA mark that is not a letter or number, such as ! or # or ?
- PrivateKept to yourself. Private details are things you do not share online.
- GuessTo try to work something out without being told. Weak passwords are easier to guess.
- MemorableEasy to remember. A silly sentence is memorable.
How to use it
- Print both pages. Page 1 is for your child. Keep page 2 for the grown-up.
- Read the four stamp rules together. Make sure your child knows what each one asks for.
- Work through the activity together the first time. Talk about each choice your child makes.
- Check against the notes on page 2 and the answers. Ask your child to explain why each stamp was earned or missed.
- Come back to it another day. Repeating a familiar activity builds confidence.
Help, stretch and game ideas
If it feels too hard
Let your child say each sentence aloud and point to the first letter of every word before writing. Count characters on fingers or tap each one with a pencil. Do one stamp at a time, and check each rule before moving to the next.
To stretch confident children
Ask your child to explain why a long password made of common words can still be guessed more easily than a silly one. They could then invent a new silly sentence and test it against all four stamps.
Make it a game
Swap sheets with a partner. Each player tries to crack the other's pretend password, then awards stamps for every rule it meets. Talk about which stamp was hardest to earn and why.
Mistakes to watch for
Watch forA child counts the characters wrongly and thinks the password is long enough.
Try thisWrite one character per box, or tap each character with a pencil as you count aloud.
Watch forA child reaches 12 characters by repeating the same letter or number.
Try thisExplain that repeated patterns are easy to guess. Use more words in the sentence instead.
Watch forA child adds a pet name or a school to make the password easy to remember.
Try thisRemind them of the PRIVATE stamp. Make the sentence silly instead, so it is memorable without personal details.
Talk about it
- Who is it safe to share a password with, and who is not?
- Why might a short password be easier to crack than a long one?
- What makes a sentence silly and easy to remember?
- Which stamp did you find hardest to earn?
- What details about you might other people be able to guess?
- How could you explain the four stamps to a younger child?

Secret code sentences
Make up three silly sentences. Write the first letters of each one as a code, then swap with a friend and try to guess the sentence.
Character counting
Choose any short phrase and write one character in each square of squared paper. Count them and see how many more you need to reach 12.
Safe or private sort
Write personal details on small pieces of paper, such as a name or a favourite colour. Talk together about which ones belong in a password and which do not.
Who it is for
Parents
Sit with your child for the first go and let them lead. Talk through each stamp rule. Praise the thinking as well as the finished password, and remind them to use only pretend passwords on the sheet.
Teachers
Use it as a starter or plenary in an online safety lesson, or as an early finisher or homework task. It needs no preparation beyond printing. Page 2 has support and stretch ideas for mixed ability groups.
Home educators
Pair it with everyday talk about staying safe online. Siblings can swap sheets and try to crack each other's pretend passwords. Come back to it for revision a few weeks later.
Where this fits in computing
Before this sheet, children learn to use devices and online tools with adult help. They begin to understand that some information should stay private. Password Passport turns that idea into a clear set of rules they can apply.
After this, children can move on to wider online safety in Years 5 and 6. They think about how they use technology safely, respectfully and responsibly, and who to tell when something online worries them.
