How does this work?

This tool uses the Have I Been Pwned API to check if a domain has appeared in known data breaches. The service aggregates data from hundreds of breaches and makes it searchable.

Domain Check (Free): Shows all breaches that affected a particular domain (e.g., adobe.com, outlook.com, yahoo.com). This tells you if the service you used had a breach, which means your account may be at risk.

Email Check (Requires API Key): Searches for specific email addresses in breach databases. The Have I Been Pwned API requires an API key ($3.50/month) for email-specific checks. You can check your email directly at haveibeenpwned.com for free.

Tip: If you want to know if your account might be compromised, check the domain of your email provider or services you use. For example, if you use Outlook, check "outlook.com" or "hotmail.com".
