Answer Key

Setting up MFA with an authenticator app

Section A: Quick Questions

A — Open the account's security settings

B — Choose 'Authenticator app' as the MFA method

A — Scan it with the authenticator app

A — Enter the first one-time code from the app

B — About every 30 seconds

Section B: Match the Pairs

Settings > Security > Two-step verification → The menu path where a student starts turning on MFA for an account

Scan the QR code with the app → Links the authenticator app to the account so it can make one-time codes

Setup is only finished when you enter the first code from the app to prove it works → Enter the 6-digit code to confirm

An authenticator app shows a new one-time code that changes every 30 seconds → code_valid_for = 30 seconds

Turn on MFA, then close the page without entering a code → The first one-time code was never entered, so the setup was not confirmed and MFA may not be switched on.

Write down today's code to use again next week → Authenticator codes change every 30 seconds, so a saved code will not work later.

Section C: Definitions

authenticator app setup — Open security settings, choose an authenticator app, scan the code, then enter the first one-time code to confirm. Codes change every 30 seconds.

Section D: Fill in the Blanks

scan("setup code")

scan("setup code")
enter(first_code)

repeat every 30 seconds
    new_code()

open("security settings")
choose("authenticator app")

Section E: Spot the Error

B — To set up MFA with an app, you choose an authenticator app, not a security question. Line 2 should be: choose authenticator app.

D — You must enter the first one-time code to confirm the setup worked. Skipping it means MFA is never confirmed. Line 4 should be: enter the first code.

C — The setup code links the app to your account, so it must stay private. You scan it yourself with your own phone. Line 3 should be: scan the QR code.

C — Authenticator app codes change every 30 seconds, not every 30 days. Line 3 should be: wait 30 seconds.

C — To confirm setup you enter the first one-time code shown in the app, not your old password. Line 3 should be: enter the first code.
