Data breaches happen constantly, often without the affected company notifying users directly or promptly.

Checking Your Exposure

Reputable breach-checking tools let you enter an email address and see which known breaches it has appeared in, without needing to enter a password. This takes under a minute and covers most major publicly disclosed breaches.

What to Do If You Are Exposed

Change the password for any affected account immediately, and check whether that same password was reused anywhere else. Turning on two-factor authentication wherever available adds a strong layer of protection even if a password is compromised again in the future.

Checking every few months is a quick habit that catches exposure early, before it turns into a bigger problem.
