Have I Been Pwned?

 

Have I Been Pwned lets you check to see if you have an e-mail address (account) that has been compromised in a data breach. 

In a major data breach (such as Yahoo or Equifax) millions of accounts can be compromised. Even a minor data breach can compromise tens of thousands of accounts. 

Check to see if your e-mail has been included in a data breach and if it has consider getting a new e-mail address from a more secure provider (such as ProtonMail).
