Data Breach Checker

Check if your email has been exposed in data breaches

Alias Email does not store or share your email address

What if my email was exposed in a data breach?

If your email was part of a data breach, it means hackers might have access to your address — and possibly your password, name, or other details. This can lead to spam, phishing attempts, or even unauthorized access to your accounts.

Here's what to do:

  1. Change your password immediately, especially if you've reused it elsewhere
  2. Enable two-factor authentication on all important accounts
  3. Watch out for suspicious emails or login attempts

To better protect yourself in the future, start using email aliases. With Alias Email, you can generate unique addresses for every service you use. If one gets compromised, just disable it — no need to change your main email or risk further exposure.

Monitor your accounts to stay safe

Data breaches are happening more frequently, compromising millions of accounts each year. Our free data breach monitoring tool helps you stay aware of potential security threats to your online identity.

Frequently asked questions

What is a data breach?
A data breach occurs when sensitive, protected, or confidential data is copied, transmitted, viewed, stolen, or used by an individual unauthorized to do so. This can include personal information like email addresses, passwords, credit card numbers, and other private data.
How does the data breach checker work?
Our data breach checker checks your email address against a comprehensive database of known data breaches. We search through billions of compromised records to see if your email has been exposed in any security incidents.
What should I do if my email is found in a breach?
If your email is found in a breach, immediately change your passwords for all accounts using that email address. Enable two-factor authentication where possible, monitor your accounts for suspicious activity, and consider using a password manager to create strong, unique passwords.
Is my email address stored when I check for breaches?
No, we do not store or share your email address. The check is performed securely and your email is not saved in our systems. We prioritize your privacy and security.
How often should I check for data breaches?
We recommend checking your email addresses for data breaches at least once every few months. You should also check immediately if you receive a notification from a service about a potential security incident.
What types of data breaches are included in the search?
Our database includes breaches from major websites, social media platforms, e-commerce sites, financial institutions, and other online services. We continuously update our database with new breach information as it becomes available.
