Find out if your passwords are leaked, and generate unbreakable ones instantly. Your full password never leaves your device.
Breach checks use k-anonymity. Only the first 5 characters of a SHA-1 hash ever leave your device — never the password itself.
See in seconds if a password appears in known breaches, with an exact exposure count.
Standard, Memorable, WiFi, and PIN presets, with a real-time strength meter as you type.
History stored as hashes only, clipboard auto-clear after 60 seconds, and app-switcher blur.
Optional email breach monitoring, built the same privacy-first way as password checks.
iPhone, iPad, Mac, Apple Watch, widgets, Live Activities, and Siri Shortcuts — all native.
LeakGuard hashes your password on your device, sends only a 5-character prefix to Have I Been Pwned, and matches the result locally. The full password — and the full hash — never leave your iPhone.
