Every feature below ships in the current version of LeakGuard on the App Store, unless marked otherwise.
Check any password against billions of leaked credentials via Have I Been Pwned's k-anonymity API. Your full password never leaves your device — only a 5-character hash prefix is sent.
Generate cryptographically secure passwords from 8–64 characters, with control over uppercase, lowercase, numbers, symbols, and excluding ambiguous characters.
A live 0–100 score with a checklist, so you see exactly what's making a password weak — or strong — as you type.
Review past checks without re-exposing anything: history is stored as a SHA-256 hash only, with 90-day retention.
Copied passwords automatically clear from your clipboard after 60 seconds — no manual cleanup needed.
LeakGuard blurs itself in the app switcher, so sensitive content isn't visible in a glance or a screenshot.
Sign in with Apple, Google, or email — or skip sign-in entirely and use LeakGuard anonymously.
Ask a Gemini-powered assistant about breaches, privacy, and staying safe online. Scoped to security topics only.
Generate and check passwords right from your wrist.
Home Screen, Lock Screen, and Watch complications showing your security score.
Watch a breach scan's progress right on your Lock Screen and Dynamic Island.
"Hey Siri, check my password" — hands-free, no app open required.
LeakGuard also runs natively on iPad, Mac (via Catalyst), and visionOS.
An 11-step onboarding walks you through what LeakGuard checks and why, using a demo password so you see exactly how a breach check works before you ever type a real one.
