Safeguards That Work: Passwords, Two-Factor, and Device Security
Grade 8 · Cybersecurity & AI Education · NYS 7-8.CY.2 · 40 Minutes
NYS-Aligned Standard
7-8.CY.2 — Describe physical, digital, and behavioral safeguards that can be employed in different situations. NYS Computer Science and Digital Fluency Learning Standards (2020)
Learning Objectives — “I Can” Statements
- I can classify safeguards as physical, digital, or behavioral.
- I can recommend appropriate safeguards for a specific situation.
- I can explain how two-factor authentication adds protection beyond a password.
Essential Question
Which safeguards fit which situation — and why does layering them matter?
Student Worksheet
Part A — Sort the Safeguards (10 min)
Label each safeguard P (physical), D (digital), or B (behavioral):
- Locking the screen when you walk away
- Using a password manager
- Keeping a laptop in a locked cabinet
- Turning on two-factor authentication (2FA)
- Not reusing the same password on different sites
- Installing software updates
- Covering a webcam with a slide
- Logging out of a shared computer
Part B — Match Situation to Safeguard (12 min)
For each scenario, name the best safeguard and the category:
- A shared family tablet is used by everyone.
- A phone is taken to school and left in a locker.
- An account holds important schoolwork and photos.
- A public library computer is used to check email.
Part C — Explain 2FA (10 min)
In 3–4 sentences, explain what two-factor authentication is and why a stolen password alone is not enough to break into a 2FA-protected account. Use the words something you know and something you have.
Part D — Reflection (8 min)
Choose one safeguard you do not currently use and write a plan to start using it this week.
SDI & Differentiation Block
Supports for MLLs/ELLs
Entering/Emerging (NYSESLAT Levels 1–2):
- Provide category icons (lock = physical, shield = digital, person = behavioral).
- Sentence frame: “This safeguard is ___ because ___ .”
Transitioning/Expanding (NYSESLAT Levels 3–4):
- Pre-teach: safeguard, physical, digital, behavioral, authentication, update.
- Provide a 2FA sentence starter: “Two-factor authentication means ___ and ___ .”
Supports for Students with IEPs
SDI Adaptation Dimensions: content, delivery
- Content: Reduce Part A to 5 items; provide a word bank for Part B.
- Delivery: Read items aloud; allow verbal or typed responses; extend time.
Suggested Placement: ICT, Resource Room
Answer Key / Model Responses
Part A: 1-B, 2-D, 3-P, 4-D, 5-B, 6-D, 7-P, 8-B. Part B (sample): shared tablet → separate user profiles/logging out (behavioral/digital); phone in locker → device passcode + locked locker (digital + physical); important account → strong password + 2FA (digital); public library computer → log out + don’t save password + private window (behavioral). Part C model: “Two-factor authentication requires something you know (a password) plus something you have (a code on your phone). A thief with only the password is still blocked because they don’t have the second factor.”
