OneSecret — Password Generator

OneProduct Studio

About this app

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.
