UniKey: Your Secure, Deterministic Password Manager

UniKey is a powerful password manager that generates unique passwords for all your accounts without storing them. Using secure algorithms, UniKey creates strong passwords deterministically from your master password and login information — no cloud sync needed, passwords are always available when you authenticate.

How It Works

UniKey combines your master password with login item details (name, optional email/username, and optional phrase) to generate unique passwords using secure algorithms. The same inputs always produce the same password, so you can regenerate any password anytime, anywhere. Your master password is the only secret you need to remember.

Key Features

• Deterministic Password Generation: Generate unique, strong passwords on demand. No password storage needed — passwords regenerate instantly when you authenticate.
• Master Password Protection: Stored securely backed by platform-specific secure storage.
• Biometric Authentication: Unlock quickly with biometrics. Biometric-protected storage ensures your master password is only accessible after successful authentication.
• Organize with Groups: Organize login items into custom groups. Switch between groups easily and keep accounts organized by category or service type.
• Customizable Password Options: Configure default settings including length, character types, minimum requirements, and ambiguous character avoidance. Each login item can have custom options.
• Password Phrases: Add optional phrases to generate different passwords when needed — perfect when a site's password was compromised.
• Secure by Design: Rate limiting prevents brute force attacks. Inactivity timeout automatically locks the app. Time tampering detection and constant-time password comparison prevent security bypasses.
• Privacy First: All password generation happens locally. No passwords are transmitted over the network. Only login item metadata (names, groups, settings) sync — actual passwords never transmitted.
• Easy to Use: Simple interface to add, edit, and manage login items. Copy passwords with one tap, toggle visibility, and organize with groups.

Perfect For

• Users who want strong, unique passwords without managing a password vault
• People who need access across devices without internet connectivity
• Security-conscious users who prefer deterministic generation over cloud storage
• Anyone wanting password manager convenience with local-only generation

Getting Started

1. Set your master password when you first launch
2. Add login items for each account or service
3. Optionally customize password options per item
4. Copy generated passwords when needed
5. Organize items into groups

Security Notes

• Never share your master password
• If you forget your master password, you lose access to all generated passwords
• Use biometric authentication for added security and convenience
• App automatically locks after inactivity
• Failed attempts are rate-limited to prevent brute force attacks

Privacy & Data

UniKey is designed with privacy in mind. Password generation happens locally. Login item metadata may sync via Android backup, but master password and generated passwords are never stored in the cloud or transmitted.
