Was my email in a breach?

The free check asks Have I Been Pwned about one address and shows the result. We never store or log the address.

What to do after a breach

  • Change the password on that service, and anywhere you used the same password. A password manager makes this painless.
  • Turn on two-factor sign-in on that service and on your email.
  • Warn staff: emails, texts or calls quoting leaked details are not proof the sender is genuine.
  • If card or bank details leaked, watch statements and tell the bank; if identity documents leaked, consider a credit ban or alert.

Hear when a breach touches your business

Free: an alert when a service you use is breached. Breach Watch: your staff addresses checked after every new breach.
