Lock Mac files in Finder with Touch ID & AES-256
FinderLock is a native macOS app that lets you lock any file or folder in Finder with Touch ID or a password. AES-256 encryption — the same standard used by banks. Unlike FileVault (full-disk only), FinderLock protects individual files with one click. Double-click to unlock, auto-lock when idle, and lock icon badges right in Finder. Everything stays on your Mac. No accounts, no cloud, no telemetry. Free plan included. One-time purchase — no subscription.
