Data Leak Checker
Find out if your email or password has appeared in known data breaches. Two modes: password uses k-anonymity (only 5 hash chars leave your device). Email uses the Have I Been Pwned public API with your address — best used with the password mode for full privacy.

What "Pwned" Means
HIBP aggregates publicly-leaked data dumps from breaches. If your address appears, it was part of a leak — your password may have been exposed in cleartext or as a weak hash. Action: change the password everywhere it was reused, enable 2FA, and consider rotating to an alias.
