✅ What the Results Mean

  • Red banner = Your info was found in one or more breaches
  • Green banner = Nothing found (but doesn’t guarantee safety)
  • Breach list = Where your data leaked, what was exposed (email, password, phone, etc.)

 


 

🔄 Step 2: Take Action (If You’ve Been Pwned)

If you see your info in a breach — here’s what to do right away:

🔐 1. Change Your Password

Especially if it was reused on other sites. Use a new, strong one (see How-to #3).

 

🔑 2. Turn On Two-Factor Authentication

Add 2FA to the account that got breached — and your email too.

 

🔁 3. Check for Reuse

Did you use the same password elsewhere? Change those too.

 

🧼 4. Clean Up Old Accounts

If it’s an account you no longer use (like MySpace or Adobe), consider deleting it entirely.

📬 Step 3: Monitor for Weird Activity

 

  • Watch for phishing emails pretending to be from breached companies

     
  • Check your spam folder for password reset attempts you didn’t request

     
  • Sign up for breach alerts (HaveIBeenPwned lets you register your email for future notifications)

🧠 Pro Tips

 

  • Use a password manager to avoid reusing passwords

     
  • Never click password reset links from sketchy emails — go directly to the site

     
  • Enable login alerts wherever possible

     


TL;DR — What to Do If You’ve Been Breached

✅ Check HaveIBeenPwned

✅ Change affected passwords

✅ Turn on 2FA

✅ Delete unused accounts

✅ Monitor your inbox for shady stuff
