About LockBox Password Manager
LockBox is a privacy-focused Chrome password manager extension:
• Zero-knowledge encryption: master password and PIN are never stored in plain text; vault uses local AES-GCM
• Password generator: customizable length and character sets
• Credential save & fill: fill saved logins from in-field controls
• Profile autofill: save name, email, phone, address for one-click form filling
• Quick PIN unlock for everyday use
• Biometric unlock on supported devices (Touch ID, Face ID, Windows Hello)
• Fully local: no cloud sync, no analytics servers, no remote vault
Built for users who want passwords and autofill data to stay on their own computer.
