OneSecret — Password Generator

OneSecret — deterministic password generator and local password manager that keeps full control of your secrets on your device. How it works • Deterministic generation from three inputs: site + login + your secret word. • Two modes: generate-on-the-fly (no saving) or save an entry (you may save an entry without storing the secret word). • Secret word is NEVER stored. If an entry is saved without a stored password, you can deterministically restore that password by entering your secret word. Security & privacy • All data remains on the device only — no cloud sync, no external servers. • Saved entries are encrypted using Android security primitives (Android Keystore, AES/GCM). • Biometric authentication (BiometricPrompt) is used only to unlock access; biometric data is handled by the system and never leaves the device. • No analytics, no advertising SDKs, no data sharing. Why use OneSecret • Generate unique, site-specific strong passwords without memorizing them. • Keep private control: secret word never stored, saved records encrypted locally. • Lightweight and offline-first — minimal permissions and maximum privacy. Notes • The app produces deterministic, site-specific passwords using a secure key-derivation step (scrypt) and a fixed output format. • Intended for adult users (18+) and not targeted at children.
