Data Breach Scanner
Check if your personal email and password have been compromised by hackers and leaked online.
Where these databases come from
When a site gets hacked, the stolen login-password database rarely stays with one attacker — it spreads across forums and ends up in massive combined archives holding billions of "email:password" pairs from thousands of breaches over the years. This check compares your address against exactly those archives.
Why this matters even if that password is long gone
It's not about that one password — it's about the pattern. If the leaked password resembles what you use on other sites now (same base with a different number at the end — a classic), that's a direct hint to an attacker about what to try next.
What to do if your email turns up in a breach
First, change the password everywhere it repeats, starting with your email. Then work through the rest in order: banks, password manager, social media. The full prioritized plan is in the article below.
