Check if your password has been compromised in a data breach. Our free password breach checker, scans over 847 million leaked passwords to help you stay safe online. Instantly discover if your password has been exposed and get actionable security recommendations.
Securely checking password against 847+ million pwned passwords...
847+ million passwords in the Pwned Passwords database
12+ billion account credentials compromised across all breaches
81% of hacking breaches involve stolen or weak passwords
65% of people reuse passwords across multiple sites
New breaches discovered weekly adding millions more passwords
Credential Stuffing Attacks Hackers use automated bots to test leaked passwords across thousands of websites. If your password is pwned, attackers are actively trying it on popular sites like Gmail, Facebook, Amazon, and banking portals.
Account Takeover One compromised password can cascade into multiple account breaches if you reuse passwords. Hackers gain access to one account and use it to break into others.
Identity Theft Breached credentials combined with other leaked data (email, phone, address) enable identity theft, financial fraud, and targeted phishing attacks.
Dark Web Sales Pwned passwords are sold in bulk on dark web marketplaces within hours of being breached. Your password could be in a list being sold for as little as $10.
When your password appears in the database, you'll see how many times it was found in breaches. Here's what the numbers mean:
1-1,000 occurrences: Moderately compromised—change immediately
1,000-100,000 occurrences: Highly compromised—commonly used by hackers
100,000+ occurrences: Extremely dangerous—in every attacker's toolkit
"123456" - Seen 37+ million times
"password" - Seen 10+ million times
"123456789" - Seen 7+ million times
"qwerty" - Seen 3+ million times
Never use these or similar simple passwords on any account.
If your password doesn't appear in the database, that's excellent news! However, this doesn't guarantee 100% security. Always follow password best practices:
Use unique passwords for every account
Make passwords at least 16 characters long
Use a mix of uppercase, lowercase, numbers, and symbols
Enable two-factor authentication everywhere
Check regularly as new breaches are discovered
Don't just update the password on the site you were checking. Change it on every single site where you've used this password or any variation of it. Hackers test similar patterns.
Check recent login history on all affected accounts
Look for unfamiliar devices or locations
Review account activity for suspicious transactions
Check for unauthorized changes to settings or recovery options
Add 2FA to every account that supports it, especially:
Email accounts (Gmail, Outlook, Yahoo)
Financial services (banks, PayPal, investment accounts)
Social media (Facebook, Instagram, Twitter)
Cloud storage (Google Drive, Dropbox, iCloud)
Shopping sites (Amazon, eBay)
Use authenticator apps (Google Authenticator, Authy, Microsoft Authenticator) instead of SMS when possible—they're more secure.
Set up account alerts for unusual activity
Watch for unexpected password reset emails
Check credit card and bank statements weekly
Consider credit monitoring services if financial data was at risk
Use a Password Manager Password managers are essential for modern security. They:
Generate cryptographically strong, random passwords
Store passwords in encrypted vaults
Auto-fill passwords to prevent phishing
Alert you when passwords appear in new breaches
Work across all your devices
Popular options: 1Password, Bitwarden, Dashlane, LastPass, NordPass
Create Strong Passwords If you must create passwords manually:
Minimum 16 characters (longer is better)
Random combinations of uppercase, lowercase, numbers, symbols
Avoid dictionary words, personal information, or patterns
Never Reuse Passwords Each account needs its own unique password. Password reuse is the #1 reason people get hacked. One breach shouldn't compromise your entire digital life.
Regular Security Checkups
Check passwords monthly with our breach checker
Update old passwords every 6-12 months
Remove unused accounts and services
Review app permissions and connected services
Strong passwords share these characteristics:
Length: 16+ characters minimum (20+ is ideal)
Randomness: Unpredictable combinations, not dictionary words
Uniqueness: Different for every single account
Complexity: Mix of uppercase, lowercase, numbers, symbols

Don't risk using weak or pwned passwords. Use our generator to create unbreakable passwords in seconds.
Yes, absolutely. Your password is hashed locally in your browser using SHA-1 before any data is transmitted. We use the k-Anonymity model, sending only the first 5 characters of the hash to the Have I Been Pwned API. Your actual password never leaves your device, and neither we nor HIBP ever see it.
We use the official Have I Been Pwned Pwned Passwords API. Your browser creates a SHA-1 hash of your password, sends the first 5 characters to the API, receives back all matching hash suffixes, then checks locally if your full hash is in the results. This k-Anonymity approach is the same technology used by major password managers.
"Pwned" is internet slang meaning "owned" or "compromised." In cybersecurity, if your password has been "pwned," it means it appeared in a data breach and is now publicly available to hackers.
Not necessarily. It means that specific password appeared in a past data breach somewhere. If you've already changed your password since the breach occurred, your account may be secure. However, you should verify there's been no unauthorized access and ensure you're not using that password anywhere else.
Yes, very much. The count shows how widespread the compromise is:
The higher the count, the more actively it's being used in attacks.
HIBP is a free service created by security researcher Troy Hunt in 2013. It aggregates data from hundreds of breaches affecting billions of accounts. The Pwned Passwords component contains 847+ million unique passwords exposed in real breaches.
