Frequently Asked Questions

A data breach occurs when personal information — such as emails, passwords, names, and even documents — is exposed without authorization. This can happen when hackers break into company systems, when employees mishandle sensitive data, or when databases are left unprotected on the internet. Thousands of breaches have been documented, affecting billions of people worldwide.

We use automated robots and artificial intelligence specialized in continuously monitoring known breach databases and areas of the internet where exposed information tends to circulate. Our technology cross-references this information with the email you provide and identifies whether your data has appeared in any known breach.

Yes, personal checks are 100% free, with no limits and no account required. You can check as many emails as you want, whenever you want. For businesses that need continuous monitoring at scale, we offer corporate plans upon request.

No. PassMonitor works without registration. Just enter your email, confirm the verification code we send, and within seconds you'll see your results.

To protect your privacy. We only allow the actual owner of the email to see the breach results. The code we send is temporary, expires in 5 minutes, and serves as proof that you truly have access to that inbox.

We do not store your email after the check, and we never ask for or store passwords. The entire process uses end-to-end encryption, and data is processed in real time without any permanent retention.

It means that at some point, a service or website where you registered was hacked and user data — including yours — was exposed. Depending on the breach, your email, password, full name, address, phone number, or even financial data may have been exposed. This doesn't mean someone has already used your data, but it means it's available for potential misuse.

First, immediately change the password for the affected service. If you used the same password on other sites, change those too. Enable two-factor authentication (2FA) on all important accounts — especially email, banking, and social media. Watch for suspicious emails and messages in the coming weeks, as scammers may try to use your data in phishing attempts.

Not necessarily. An "all clear" result means your email was not found in the breaches our systems monitor so far. However, there may be breaches that haven't been discovered or made public yet. That's why we always recommend maintaining good security practices: unique passwords, two-factor authentication, and periodic checks.

The Deep Web is a layer of the internet that doesn't appear in search engines like Google. It's where most leaked data ends up circulating, often without the victims' knowledge. Our automated robots continuously monitor these areas to identify new breaches and alert you as quickly as possible.

The Deep Web is everything not indexed by search engines — it includes corporate intranets, academic databases, and login-protected areas. The Dark Web is a specific part of the Deep Web accessible only through special browsers (like Tor), where leaked personal data often ends up being shared or exposed.

Use a different password for each site or service — if one leaks, the others stay protected. Enable two-factor authentication (2FA) whenever possible. Use a password manager like Bitwarden or 1Password to automatically create and store strong passwords. Avoid clicking links in suspicious emails and periodically check if your data has appeared in new breaches.

Two-factor authentication adds an extra layer of security: beyond your password, you need to confirm access with a second factor — usually a temporary code on your phone. Even if someone discovers your password, they can't access your account without this second code. It's one of the most effective ways to protect yourself against unauthorized access.

Yes. PassMonitor is fully responsive and works on any device — smartphone, tablet, or computer. No app installation is needed.

We recommend checking at least once a month, or whenever you hear news about major data breaches. Since new breaches are discovered constantly, periodic checks help keep you informed and ready to act quickly.

The check is done by email, but the results show what types of data were exposed in each breach — including whether passwords, names, addresses, phone numbers, or financial data were among the compromised information.

This can happen for several reasons: the site may have changed its name since you registered, your data may have been sold or shared between services without your knowledge, or someone may have used your email to create an account without your permission.

Unfortunately, no. Once data is leaked and spreads across the internet, it's virtually impossible to completely remove it. What PassMonitor does is inform you about which data was exposed so you can take protective measures — like changing passwords and enabling two-factor authentication.

Yes! We offer corporate solutions including continuous domain monitoring, real-time alerts, API integration, and AI-generated automated reports. Companies can check whether employee credentials have been exposed and act before an attack happens. Learn more on our For Business page.

Yes. PassMonitor only analyzes information that is already publicly known — data that has already been exposed and circulates in known databases. Our goal is exclusively to inform and protect users, never to facilitate the misuse of personal data.
