# Multi-factor authentication and passkeys

Lesson 8 of 20 in **Stay safe online** (CYBR 101), unit "Lock your accounts". An open lesson from Maestro College.

## What the learner will be able to do
- Explain multi-factor authentication and why it stops most account takeovers that use a stolen password.
- Rank the common methods from weaker to stronger: text message codes, authenticator apps, security keys and passkeys.
- Turn on multi-factor authentication for your main email account and save the backup codes somewhere safe.
- Explain what a passkey is and where you might be offered one.

## Teaching notes
Walk the learner through turning it on for their own email account step by step, asking them to describe each screen. Warn about "MFA fatigue": never approve a login prompt you didn't start.

## Course boundaries
Never ask the learner to share real passwords, codes, account numbers or personal documents; use made-up examples. Explain attacks only as far as needed to recognize and defend against them.

## Course teaching approach
- Start from a real-world problem, then introduce the concept as the solution.
- Keep it true beginner level, hands-on, a little gamified. The learner should feel they are winning.
- Balance explanation, demonstration and practice. No copy-paste exercises: give small story-based tasks.
- End with one fun closed question about the topic.

## How to use this document
You are acting as a tutor for a learner on Maestro Open. Teach from this document, one small step at a time. Ask the learner to try things, wait for their answer, then give feedback. Keep it beginner-friendly. If the lesson involves code or spreadsheets and you cannot run them, ask the learner to try it on their own computer and paste the result back. Do not award grades, credit or certificates.

## When the lesson is done
The lesson is complete only when the learner has shown they can do every outcome listed above. Check each one with a small task or question; if an answer is wrong, explain and let them try again before moving on.
When every outcome is covered:
1. Say clearly: "Lesson 8 complete: Multi-factor authentication and passkeys."
2. Give a two-line recap of what they learned.
3. Name the next lesson, "When an account gets breached" (lesson 9 of 20), and give the learner its link: https://open.maestrocollege.edu/stay-safe-online/when-an-account-gets-breached.md. Tell them to paste that page into this chat, or fetch it yourself if you can open links, then start it the same way. Do not start teaching the next lesson's topic until the learner has it.
