1. Visit haveibeenpwned.com/Passwords
2. Enter your password in the search field
3. Click "Search"

This password check is performed securely using k-anonymity, meaning your full password is never sent to Have I Been Pwned servers.

Understanding Your Have I Been Pwned Results

Different types of breaches carry different risks, and Have I Been Pwned provides valuable context about each breach to help you assess the potential impact. Interpreting Have I Been Pwned results correctly allows you to prioritize your response actions.

Types of Breaches Reported by Have I Been Pwned

Have I Been Pwned results provide details about each breach, including:

• Breach name: The service or website that was compromised
• Breach date: When the breach occurred
• Data types exposed: What kind of information was compromised

Decoding Data Types in Have I Been Pwned Results

Different data types reported by Have I Been Pwned present different levels of risk:

1. Email addresses: May lead to increased spam or phishing attempts

Understanding which data types were exposed in each breach reported by Have I Been Pwned helps determine the severity of the risk and informs what protective measures you should take. The more sensitive the exposed information reported by Have I Been Pwned, the more aggressive your response should be.

Tailored Action Plans Based on Have I Been Pwned Results

After checking Have I Been Pwned, your next steps should be determined by what information was exposed. Different exposure scenarios require different responses. Have I Been Pwned provides the information you need to create an appropriate action plan based on breach severity. Here are recommended response plans for different levels of exposure identified by Have I Been Pwned.

Level 1: Email-Only Exposure on Have I Been Pwned

If Have I Been Pwned shows only your email address was exposed:

• Be more vigilant about phishing attempts targeting that email
• Consider using an email filtering service for additional protection
• No need to change passwords if they weren't exposed in the breach
• Continue monitoring your Have I Been Pwned results for new breaches

Email-only exposures reported by Have I Been Pwned present the lowest risk but still warrant increased awareness. While no immediate password changes are necessary, these breaches often lead to increased targeting for phishing attacks attempting to capture your credentials. Remaining alert after an email exposure on Have I Been Pwned is your best defense.

Level 2: Email + Password Exposure on Have I Been Pwned

When Have I Been Pwned shows both email and password were compromised:

• Immediately change the password on the affected service

• Enable two-factor authentication (2FA) where available
• Consider using a password manager to generate and store unique passwords
• Set up Have I Been Pwned notifications for future alerts

Password exposures identified by Have I Been Pwned require immediate action. The greatest risk comes from password reuse across multiple services, as attackers often try exposed credentials on popular websites. Implementing unique passwords for each service prevents a single breach from compromising multiple accounts. Have I Been Pwned notifications can alert you to future exposures.

Level 3: Sensitive PII Exposure on Have I Been Pwned

For breaches containing significant personal identifiable information (PII) reported by Have I Been Pwned:

1. Complete all Level 2 actions immediately
2. Place fraud alerts with major credit agencies
3. Monitor financial statements and credit reports regularly

6. Be vigilant for signs of identity theft or fraud

When Have I Been Pwned reveals extensive personal data exposure, comprehensive protection measures become necessary. This level of breach significantly increases your risk of identity theft and financial fraud. Taking decisive action promptly after discovering such an exposure on Have I Been Pwned can prevent more serious consequences.
