How to find out in 2 easy steps if your data was exposed in an online breach

A website called "Have I been pwned" can help internet users determine if their data has been exposed in an online breach.

Maintained by security analyst Troy Hunt, the database on haveibeenpwned.com, lets you check if one of your email addresses or passwords has been compromised, or "pwned," in internet speak.

After typing the website into your browser, you just have to type in the address of the email account you wish to check for breaches. The site cross-references that email address with more than 10 billion accounts compromised in past breeches.
