How to Check If Your Password Has Been Leaked

"This password has appeared in a data breach" — have you seen this warning on your phone or browser? Many people dismiss it, but this is not a notification you should ignore.

In 2024, RockYou2024 exposed roughly 10 billion passwords. The same year, MOAB (Mother of All Breaches) leaked 26 billion records. Can you be sure your password is not among them?

This article shows you how to check for breaches right now, and exactly what to do if you find one.

Your Password Is Probably Already Leaked

This is not an exaggeration — it is statistical reality.

In 2025, a Cybernews investigation found 16 billion credentials (email + password pairs) exposed online — a compilation of data stolen over the years. Data breaches are hitting record numbers every year. The question is not whether your password has been leaked, but whether you know about it.

If you do not know your password is compromised, an attacker can use it before you change it.

How to Check Right Now

Several tools can tell you if your credentials have appeared in known breaches. Here are the most reliable ones.

Have I Been Pwned

The industry standard, run by security researcher Troy Hunt. It searches across 950+ breach databases containing over 17.5 billion accounts.

1. Go to haveibeenpwned.com
2. Enter your email address and search
3. If you see "Oh no — pwned!" your email was found in past breaches

You can also check individual passwords under the "Passwords" tab. Only the first 5 characters of the SHA-1 hash are sent to the server — your actual password never leaves your device.

NordPass Data Breach Scanner

NordPass includes a built-in data breach scanner. It automatically checks whether passwords saved in NordPass appear in known breach databases and flags compromised ones.

While Have I Been Pwned checks one email at a time, NordPass scans all your saved passwords at once. When breaches are found, you can change the password directly from the app.

Google Password Checkup

If you save passwords in Chrome, Google can check them.

1. Chrome → Settings → Passwords and Autofill → Google Password Manager
2. Run "Password Checkup"
3. Compromised, reused, and weak passwords are listed

Note: Google's "Dark Web Report" feature was discontinued in February 2026. Password Checkup itself remains available.

Apple Security Recommendations

iPhone and Mac users can check using built-in OS features.

• iOS: Settings → Passwords → Security Recommendations
• macOS: System Settings → Passwords → Security Recommendations

Warnings are categorized as "Compromised Passwords," "Reused Passwords," and "Weak Passwords."

What "Compromised Password" Warnings Mean

A "compromised password" notification does not mean your specific account was hacked.

It means "a password identical to yours was found in a publicly known data breach." Someone else using the same password had their account breached, and that password is now in attacker dictionaries.

This matters because of credential stuffing. Attackers take leaked email + password combinations and try them on other services automatically. If you reuse passwords, one breach can cascade across all your accounts.

What to Do If You Find a Breach

Follow these steps when you discover a compromised password.

Immediate Actions (Do Now)

1. Change the password on the breached service — Use 12+ characters with uppercase, lowercase, numbers, and symbols. Make it random
2. Change it everywhere you reused it — This is the most critical step. One breach can compromise every account sharing that password
3. Enable two-factor authentication (2FA) — Even if a password leaks, 2FA keeps your account safe
4. Check bank and credit card statements — Look for unauthorized transactions

Long-Term Fixes

5. Adopt a password manager — Generate and store unique random passwords for every service. You never need to memorize them. NordPass includes automatic breach scanning
6. Switch to passkeys — Where supported, eliminate passwords entirely. Available on Google, Apple, GitHub, and more
7. Set up ongoing monitoring — Register for Have I Been Pwned notifications, or use NordPass auto-scanning

How to Never Worry About Leaks Again

The root cause of password breach problems is that humans manage passwords. We reuse them. We pick easy ones. A password manager solves this.

Why NordPass

There are several password managers, but I recommend NordPass for these reasons.

Built-in breach scanner. Automatically checks your saved passwords against breach databases. One-click password changes when issues are found.

xChaCha20 encryption. A next-generation cipher beyond AES-256. Zero-knowledge architecture means NordPass itself cannot see your passwords.

NordVPN integration. NordVPN Plus plans and above include NordPass. Manage VPN and passwords under one account.

Passkey support. NordPass stores and manages passkeys — the passwordless authentication standard replacing traditional passwords.

Wrapping Up

With 10 billion passwords publicly available in 2026, assuming "it will not happen to me" is not a strategy. Check with Have I Been Pwned or NordPass right now. If you find breaches, password changes and 2FA will contain the damage. Long term, a password manager and passkeys create an environment where breaches no longer matter.
