Multi-factor authentication and digital account security take centre stage in this Grade 9 Computer Science worksheet, helping students explore how online services verify identity and protect accounts from unauthorized access. Students investigate the difference between single-factor and multi-factor authentication, identify common authentication factors, and explain why an additional verification step makes a stolen password less useful to an attacker.

🔐 What Students Explore

The resource builds essential cybersecurity vocabulary and connects each concept to familiar digital login situations. Students examine:

• Authentication and verification: Define these processes and distinguish their roles in checking a user's identity.
• Authentication factors: Recognize something a person knows, such as a password; something a person has, such as a registered phone; and something a person is, such as a fingerprint.
• Single-factor authentication: Explain how password-only login systems work and why guessed, reused, or exposed passwords create security risks.
• Multi-factor authentication (MFA): Describe how combining different forms of proof provides an additional barrier to unauthorized account access.
• Responsible account security: Identify safe practices, including protecting temporary login codes, keeping devices updated, using unique passwords, and noticing unusual login alerts.

Inside the Student Worksheet

Students move from introductory vocabulary and examples to reading comprehension, security decisions, and independent explanation. The activities include:

• Interpreting a dialogue about digital account security.
• Matching key cybersecurity terms and concepts.
• Completing a cloze paragraph using authentication vocabulary in context.
• Labelling a diagram to reinforce how authentication works.
• Reading an informational passage about passwords, authentication factors, temporary codes, and account protection.
• Answering multiple-choice questions about security risks, biometric authentication, verification steps, and safe responses to suspicious requests.
• Evaluating true-or-false statements about MFA and responsible password practices.
• Writing short constructed responses that explain authentication factors and account protection.
• Completing an extended response comparing password-only access with password-and-device-code verification in a school learning platform scenario.

What Is Included?

• Student worksheet: A structured collection of reading, vocabulary, diagram-labelling, comprehension, and written-response activities.
• Separate Teacher Guide PDF: Includes learning objectives, teaching tips, discussion questions, and common mistakes to help teachers prepare and support instruction.

Practical Classroom Uses

Use this Grade 9 cybersecurity practice during a Computer Science lesson on digital safety, as guided reading and independent worksheet work, or as a follow-up activity after introducing online authentication. The reading passage gives students a shared foundation before they apply the concepts to different login situations. The final school-platform scenario encourages them to compare security approaches and justify their reasoning using relevant terminology.

The separate teacher guide adds practical instructional support, while the combination of recognition, comprehension, and extended writing gives students opportunities to demonstrate both factual knowledge and their ability to explain security decisions.

Why Add This Resource to Your Cybersecurity Unit?

Students encounter passwords and verification codes regularly, but may not know why services request more than one form of proof. This digital account security worksheet makes that distinction explicit. Rather than treating MFA as simply another login step, students examine the purpose of each factor, how different categories work together, and why additional verification reduces risk without guaranteeing complete protection.
