Start with a problem you want to solve. Each section explains the idea in plain English, shows why it matters, and gives you a trusted place to learn more.

ACCOUNT SECURITY

The four habits that stop common account takeovers

01

Use a unique password

Every important account needs its own long password. If one company is breached, a unique password prevents criminals from reusing it elsewhere.

02

Use a password manager

A password manager creates and stores strong passwords so you do not have to memorize or reuse them.

03

Turn on MFA

Multifactor authentication asks for another proof after your password. An authenticator app or security key is stronger than a text message when available.

04

Install updates

Updates often repair weaknesses that attackers already know about. Enable automatic updates when possible.

PHISHING & SCAMS

Pause when a message creates urgency

Phishing often impersonates a person or company you trust. The attacker wants you to react before you verify.

Unexpected urgency

“Act now,” “your account will close,” or “do not tell anyone” are pressure tactics.

A request for secrets

Legitimate support should not ask for your password, MFA code, recovery code, or remote access.

A disguised destination

The words in a link can look legitimate while opening a different website. Visit the official app or type the address yourself.

BREACH CHECK

See whether your email appeared in a known data breach

Have I Been Pwned is a public service built to help people assess exposure from known breaches. Its separate Pwned Passwords service checks whether a password has appeared in breach data without linking that password to your identity.

Never enter your password into the email-search box. Use only the separate Pwned Passwords page for a password check.
IF YOUR INFORMATION APPEARS

What to do next

  1. 1
    Read what was exposedAn email address alone requires a different response than an exposed password, Social Security number, or payment card.
  2. 2
    Change the affected passwordChange it on the breached account and anywhere else you reused it. Use a new, unique password.
  3. 3
    Secure your email firstYour email often controls password resets. Review recovery details, active sessions, forwarding rules, and MFA.
  4. 4
    Watch for targeted scamsExposed details can make fake messages sound convincing. Verify requests through a separate, trusted channel.
  5. 5
    Protect your identity when neededIf sensitive identity data was exposed, use the FTC’s recovery guidance and consider a free credit freeze.
