Troy Hunt's industry-standard breach database tracks billions of compromised accounts across thousands of incidents. We use it to tell you — in plain English — whether your email has shown up where it shouldn't.

Dropbox's open-source password checker scores strength against real-world cracking patterns — not just length and symbols. It's the gold standard for telling people whether a password actually holds up.
