If you are looking for a free data breach checker, you have two solid options: EmailLeaked and Have I Been Pwned. Both let you enter your email address and instantly find out if it appeared in a known data breach. The key difference is what happens after you get your results — EmailLeaked tells you exactly what to do next, while Have I Been Pwned gives you raw breach data and leaves the interpretation to you.
Both tools are legitimate, trustworthy, and free for basic email checks. This guide gives you an honest, side-by-side comparison so you can pick the right one for your situation — or use both.
What is Have I Been Pwned?
Have I Been Pwned (often abbreviated HIBP) was created in 2013 by Troy Hunt, an Australian web security expert and Microsoft Regional Director. It is the original data breach notification service and has become the gold standard in the industry.
HIBP allows anyone to search for their email address across a database of breaches. It also offers a separate password checker called Pwned Passwords that uses k-anonymity to check passwords without transmitting them.
Over the years, HIBP has expanded to include domain monitoring for businesses, an API for developers, and integration with password managers like 1Password. It currently tracks over 900 data breaches and roughly 14 billion compromised accounts.
What is EmailLeaked?
EmailLeaked is a free data breach checker built specifically for non-technical users. It checks your email against 962+ known data breaches covering 12 billion+ compromised records.
What makes EmailLeaked different is its focus on plain English results and actionable guidance. When your email appears in a breach, EmailLeaked does not just list the breach name and date — it tells you what data was exposed, assigns a risk level, and gives you step-by-step instructions on what to do next.
EmailLeaked also combines email breach checking and password leak checking on the same page, so you can check both without navigating to a separate tool.
How do the features compare?
Here is a side-by-side comparison of the two tools as of 2026:
| Feature | EmailLeaked | Have I Been Pwned |
|---|---|---|
| Email breach check | Free, no signup | Free, no signup |
| Password leak check | Same page, k-anonymity | Separate page, k-anonymity |
| Breach database size | 962+ breaches, 12B+ records | 900+ breaches, ~14B accounts |
| Remediation guidance | Built-in, step-by-step | Not included |
| Risk level scoring | Yes (High / Medium / Low) | Not included |
| Domain monitoring | Not available | Yes (paid) |
| API access | Not available | Yes (paid, from ~$3.50/mo) |
| Enterprise features | Not available | Yes (domain search, API) |
| Email notifications | Monthly newsletter | Per-breach alerts |
| Language | Plain English, jargon-free | Technical but clear |
| Account required | No | No (optional for alerts) |
| Data stored | Never stored | Email stored for alerts |
| Cost | 100% free | Free basic, paid API/enterprise |
How does pricing compare?
EmailLeaked is completely free with no paid tiers, no API fees, and no premium features behind a paywall. Every feature available on the site is free for everyone.
Have I Been Pwned offers a free tier for individual email lookups. Paid features include:
- Pwned 1 (basic API): approximately $3.50 per month (or $3.25/month if paid annually)
- Higher-tier API access: increased rate limits for commercial use
- Domain search subscriptions: for businesses monitoring all email addresses under their domain
- Enterprise tier: custom pricing for large organizations, identity theft protection companies, and infosec firms
If you are an individual checking your own email, both tools are free. If you are a business or developer who needs API access or domain monitoring, HIBP is the only option between the two.
When should you use EmailLeaked?
Choose EmailLeaked if:
- You want to know what to do after a breach. EmailLeaked is the only breach checker that gives you a specific action plan based on what data was exposed. If passwords were leaked, it tells you to change them. If financial data was exposed, it tells you to freeze your credit.
- You are not a technical person. Everything is written in plain English with no security jargon. Results are colour-coded by risk level so you can instantly understand how serious a breach is.
- You want to check your email and password in one place. Both checks are on the same page — no navigating to a separate tool.
- You do not want to create an account. EmailLeaked never stores your email address and never asks you to sign up for anything.
- You want a modern, mobile-friendly interface. EmailLeaked was built in 2026 with a clean, modern design optimized for mobile.
When should you use Have I Been Pwned?
Choose Have I Been Pwned if:
- You need domain monitoring for your business. HIBP lets companies monitor all email addresses under their domain, which is invaluable for enterprise security teams. This is a feature EmailLeaked does not offer.
- You need API access for development. If you are building an application that checks for breached credentials, HIBP’s API is the industry standard, used by 1Password, Firefox Monitor, and other major services.
- You want per-breach email alerts. HIBP can notify you automatically whenever your email appears in a newly loaded breach. This requires creating a free account.
- You trust established brand reputation. HIBP has been operating since 2013, has been acquired by and integrated with various security services, and is used by governments and Fortune 500 companies. That track record matters.
- You need the absolute largest database. HIBP has a slightly larger database of compromised accounts, which means it may catch some breaches that other tools miss.
How do both tools protect your privacy?
Both tools take privacy seriously:
EmailLeaked never stores, logs, or shares your email address. Your query is processed in real time and discarded immediately. Password checks use k-anonymity — only the first five characters of a SHA-1 hash ever leave your browser, so your actual password is never transmitted.
Have I Been Pwned stores your email address only if you opt in to breach notifications. The Pwned Passwords feature also uses k-anonymity, so your password is never sent to their servers. HIBP’s privacy practices are well-documented and transparent.
Both approaches are safe to use. The difference is that HIBP stores your email if you want alerts, while EmailLeaked never stores anything at all.
What are the limitations of each tool?
EmailLeaked limitations:
- No API for developers or businesses
- No domain monitoring for enterprise use
- No per-breach email alerts (newsletter only)
- Smaller database than HIBP (though both cover major breaches)
- Newer service with less brand recognition
Have I Been Pwned limitations:
- No remediation guidance — tells you what happened but not what to do
- Password checker is on a separate page
- Results can feel technical for non-security users
- Advanced features require paid subscriptions
- No risk level scoring on results
Can you use both tools together?
Yes — and many security-conscious people do exactly that. Since each tool may track slightly different breaches, checking your email on both gives you the most complete picture.
A good approach is:
- Check your email on EmailLeaked first to get actionable guidance on what to do
- Check on Have I Been Pwned to catch any additional breaches
- Sign up for HIBP notifications so you are alerted to future breaches automatically
- Subscribe to EmailLeaked’s newsletter for monthly breach roundups and security tips
Which breach checker should you choose?
Both EmailLeaked and Have I Been Pwned are excellent tools that serve different needs:
Use EmailLeaked if you are an everyday person who wants to know whether your email was breached AND what to do about it. It is the better choice for anyone who is not a security professional and wants clear, actionable guidance in plain English.
Use Have I Been Pwned if you need enterprise features like domain monitoring, API access, or per-breach alerts. It is the better choice for developers, security teams, and businesses.
Use both if you want the most thorough protection. They are complementary tools, not competitors.
The most important thing is that you check at all. According to the IBM Cost of a Data Breach Report 2025, the average data breach costs $4.44 million — but for individuals, the real cost is stolen identity, compromised accounts, and financial fraud. A free 30-second check on either tool can save you months of dealing with the fallout.
