PLECK lesson 153 · suggested week 31, day 3

Passwords and multifactor protection without secrets

Objective. Passwords and multifactor protection without secrets:apply the stated method to a concrete case,produce the requested evidence,and justify safe,private,and accessible choices.

About 25–50 minutes. The due date is chosen by a parent.

Split across sittings as needed;no timer or required date.Adult approval remains required even for independent work.

Materials: paper, pencil, optional calculator.

Use long, random, unique passwords and a reputable password manager chosen with an adult. CISA recommends at least 16 characters; multifactor authentication adds another check but does not make sharing codes safe. This lesson never asks for a real password, code, recovery key, or account access. Describe properties of a strong secret rather than submitting one you might use. No account setting changes are required. Safety and boundaries: Fictional messages, offers, and profiles only. No passwords, OTPs, account screenshots, clicking suspicious links, public posting, applications, selling, customer contact, purchases, or employer contact. Family-only evidence;use fictional details,no faces or private records.No purchases are required.

Worked example

Unscored model for discussion;use the assignment case for your own work.

A paper checklist can say“unique, long, random, stored appropriately”without displaying the secret itself.

Passwords and multifactor protection without secrets — evidence and reflection

  1. 1. Create a password-quality checklist with four properties and an adult-review note.
  2. 2. Explain why reusing one strong password across accounts creates risk.
  3. 3. A fictional caller asks for a one-time login code. Write the response.
  4. 4. Draw a two-step sign-in diagram using placeholder boxes, not actual credentials.
  5. 5. Spiral review — Rewrite“You never listen”as a specific non-blaming request in a fictional conversation. Spiral review.

Acceptance checks

An adult supervises. This stays in the family. Spending is a simulation, not real money.

For any optional food,adult verifies all ingredients and established allergy needs;avoid cross-contact,no tolerance tests,and use paper food if uncertain.For clothing/cleaning,adult checks sensitivities and labels;no chemical mixing.

Fictional messages, offers, and profiles only. No passwords, OTPs, account screenshots, clicking suspicious links, public posting, applications, selling, customer contact, purchases, or employer contact.

Complete the entire task using paper diagrams,fictional data,empty/inactive tools,and parent-observed explanation.

  • No unsupervised heat,sharp tools,cleaners,or appliances.
  • No raw-meat handling,unsafe food tasting,chemical mixing,flame/smoke experiments,or electrical repair.
  • No real childcare/medical/intimate care,financial transactions,credentials,private records,or public posting.

If this is still shaky. Use this lesson’s worked model to make a three-box process card.Label the goal,one safety/constraint check,and the evidence you would show.Explain it to a parent before trying the main task again.

Optional extra. Change one fictional constraint in this lesson,such as available time,access,ingredient restriction,or pretend cost.Revise one artifact and show what must change and what safety/privacy rule stays fixed.
