Grade 5 · Technology · Lesson 3

Strong Passwords & 2FA

Your password is the first lock on every account you own. A strong password keeps strangers out, even if they guess your name, your birthday, or your favorite team. Two-factor authentication (2FA) adds a second lock — so even a stolen password is not enough to break in.

What this lesson teaches

2Build a long, unique passphrase that is easy to remember
3Explain how two-factor authentication adds a second lock
4Match common 2FA methods to how each one works
