An email breach checker searches public data breach corpora to see if your email address has been exposed in a known leak. DragBin's checker queries the XposedOrNot breach index and lets you separately verify any password against Have I Been Pwned using k-anonymity. You get a 0-100 risk score, the list of breaches the email appears in, and the kind of data exposed. 2 ### Is this a Have I Been Pwned alternative? Our email lookup uses XposedOrNot -- an open breach data provider -- instead of HIBP's paid email API. The optional pwned password check uses HIBP's free k-anonymous Pwned Passwords API directly from your browser. Together you get a Have I Been Pwned-style answer without a paid key. 3 ### How do I check if my email is hacked? Type the email you want to check above. Your browser queries XposedOrNot directly. The tool returns a risk score, every breach the email appears in, the year of each leak, and the type of data exposed. 4 ### Does DragBin store the email I check? No. Your browser queries XposedOrNot directly -- DragBin never receives or stores your email address. We do not log, sell, or persist it. 5 ### How does the pwned password checker work? Your password is hashed with SHA-1 inside your browser. Only the first 5 characters of the hash are sent to the Have I Been Pwned Pwned Passwords API. HIBP returns every hash suffix that begins with those 5 characters and the count of times it has appeared in known breaches. Your raw password never leaves the device. This is called k-anonymity. 6 ### What does my risk score actually mean? - 0:** Clean across the index we query. - **1-30 (Low):** Older leaks, usually no credentials exposed. - **31-70 (Moderate):** Multiple breaches, often at least one password leak. - **71-100 (Severe):** Many breaches with credential leaks. Credential stuffing is likely. 7 ### What should I do if my email shows up in a data breach lookup? Rotate the password on every breached service. Replace any reused password on accounts that share that password. Turn on passkeys or two-factor authentication. Use a password manager so every future password is unique. Need a fresh password? Try the [DragBin strong password generator](/tools/strong-password-generator/). 8 ### Can attackers use this tool for credential enumeration? The data surfaced is already published in public breach corpora. XposedOrNot enforces its own global rate limits. The page is designed for one-off self checks, not bulk lookups. 9 ### Is the email breach checker free? Yes. No fees, no signup, no credit card, no ads. DragBin runs this tool as a public-good utility and as the top of funnel for our [quantum-resistant cloud storage](/post-quantum-encryption/). 10 ### Does a clean result mean my email is safe? No. A clean result means the email is not present in the public breach corpus we query. Undisclosed breaches, phishing, malware, and SIM-swap attacks won't appear here. Use unique passwords, a password manager, and 2FA regardless. ## Related security tools and reading [ ### Strong Password Generator Generate truly random or memorable passwords.
