Unit 4 Task

Create or find a classroom resource that teaches students about creating strong passwords, passcodes or passphrases.

1. Introduce the aim of the activity. Advise students that they should not share their own passwords at any time during the activity!
2. Ask the class to suggest passwords that they think people might commonly use (both combinations – e.g. ‘password’ and categories – e.g. pet names).
3. Compare their list against the most commonly used passwords in 2020
4. Explain to the students why it is important not to use a common password
5. Time to put the common passwords to the test and see how long it would take them to be cracked! Launch https://howsecureismypassword.net, enter each password and see the result.
6. Begin to use increasingly complex passwords (length and variation of characters) and see how the time frame changes. In doing this, help the students work out which numbers and symbols are easily exchangeable for letters. For example:

  •  chocolate
  • chocolatemilkshake
  • Ch0c0l@t3
  • Ch0c0l@t3M1lksh@k3!

7. Ask the students if, based on this activity, they think they should change some of their passwords? If yes, what strategies could they use make them stronger?
