    1

    Change the password on the breached account immediately

    ~15s
    Go directly to the breached company's website (do NOT click links in the breach notification email). Change your password to something new and unique — at least 12 characters long.
    2

    Change that password everywhere else you used it

    ~15s
    If you used the same password on any other account, change those too — right now. This is the #1 way hackers exploit breaches: they try your leaked password on other sites.
    3

    Enable two-factor authentication

    ~15s
    Turn on 2FA on your email account first (it controls all your other accounts), then on banking, social media, and shopping sites. Use an authenticator app over SMS if possible.
    4

    Freeze your credit at all three bureaus

    ~15s
    Visit equifax.com/personal/credit-report-services/credit-freeze/, experian.com/freeze/, and transunion.com/credit-freeze. A credit freeze is free and prevents anyone from opening new accounts in your name.
    5

    Watch for phishing emails in the coming weeks

    ~15s
    After a breach, scammers send fake "security alert" emails pretending to be the breached company. Never click links in these emails — always go directly to the website by typing the URL yourself.
    6

    Monitor your credit report

    ~15s
    Get your free credit report at annualcreditreport.com. Look for accounts you did not open, inquiries you did not authorize, and addresses you do not recognize.
