Prepared AI answer
"What makes a password strong?"
"A strong password just needs to be at least 8 characters with one capital letter and one number - that's all you need to keep any account fully safe."
Tap the claim that needs checking - is it accurate, incomplete, or misleading?

What happens in Task 4
A 10-minute Phase 3 - Investigation activity. As Group A - Password Detectives, students rank three fictional passwords from weakest to strongest, build a class passphrase rule, explain why passwords must be unique, then verify one prepared AI answer about password strength.
🎯 Learning objectives
To construct a strong, memorable passphrase, and to practise verifying AI-generated safety advice rather than trusting it automatically.
