The big idea

When coding with AI, never paste real passwords, API keys, or family info. Use fake placeholder words instead.

Some examples

Use 'YOUR_PASSWORD_HERE' as a placeholder.
Use 'your-email@example.com' as a fake email.
Never paste a real bank or game login.
AI chat may save what you typed for a long time.

Try it!

Look at any tutorial code. Notice how they use 'YOUR_KEY_HERE' instead of real keys. Copy that habit.

Here's why "Don't Paste Real Passwords Into AI Code" matters: AI can help you write, fix, and understand code faster than ever — even if you're just learning. Never paste your real passwords or keys into AI when coding — and knowing how to apply this gives you a concrete advantage.

What is the main idea of "Don't Paste Real Passwords Into AI Code"?
1. Never paste your real passwords or keys into AI when coding.
2. Use AI as the final authority for the whole decision
3. Avoid checking the answer once it sounds polished
4. Focus only on speed instead of judgment
Which concept is most central to "Don't Paste Real Passwords Into AI Code"?
1. code safety
2. secrets
3. AI coding
4. unrelated shortcut
Which use of AI fits this topic best?
1. Let the AI decide what matters without your review
2. Use the answer before checking whether it fits the situation
3. Use 'YOUR_PASSWORD_HERE' as a placeholder.
4. Trust the first answer because it sounds confident
What should a careful learner remember about "Fake the secrets"?
1. Always use fake placeholder values when sharing code with AI. Real passwords could leak.
2. Skip the context so the tool can guess faster
3. Treat the output as private even after sharing it online
4. Use the answer without checking the source
You want to use AI after this lesson. What is the safest next step?
1. Act immediately because the AI answer is written clearly
2. Use short, concrete wording and ask a trusted adult when the stakes matter.
3. Hide uncertainty so the final answer looks cleaner
4. Use private or sensitive details before checking permission
How should AI output about secrets be treated?
1. As proof that no other source is needed
2. As a replacement for context, consent, or expert review
3. As a draft or helper output that still needs human judgment and verification
4. As something that becomes correct when it sounds confident
Name one way to verify an AI answer about secrets.
Which action would help you apply "Don't Paste Real Passwords Into AI Code" responsibly?
1. Use the tool to avoid thinking through the tradeoff
2. Keep going even if the output conflicts with a trusted source
3. Trust the first answer because it sounds confident
