Password security best practices are the focus of this Grade 9 Computer Science worksheet, helping students understand how passwords, credentials, authentication, and secure account habits work together to reduce unauthorized access. Students compare weak and strong protection methods and apply safer password choices to realistic account-access and privacy scenarios. :contentReference[oaicite:0]{index=0}

Why password reuse creates risk

The lesson begins by distinguishing a password from authentication. Students learn that a password is a secret credential, while authentication is the process used to verify that a person is allowed to sign in. This vocabulary gives them a clear foundation for explaining how account protection works.

Password reuse is explored as a major security weakness. If one credential is exposed in a leak, attackers may try the same password on other services. Students compare this behavior with using unique passwords so that a problem on one account is less likely to affect others.

Secure habits students practice

• Define password, credential, authentication, and secure in context
• Compare weak password habits with stronger protection methods
• Explain why unique passwords limit damage after a breach
• Identify why credentials should remain private
• Recognize how longer, unpredictable passwords make guessing harder
• Describe the role of a trustworthy password manager

From vocabulary to account-protection decisions

A dialogue, definition-matching activity, cloze exercise, labeled diagram, and reading passage introduce the core concepts. Multiple-choice and true-or-false questions ask students to distinguish authentication from credentials, identify risky password behaviors, and choose stronger security practices. Short-answer prompts require students to explain how password security reduces unauthorized access and compare weak protection with stronger alternatives.

The extended response asks students to explain how strong password habits protect accounts while using the lesson vocabulary accurately. They compare weaker practices with stronger ones and connect unique credentials, privacy, and authentication to safer account access.
