— ENCRYPTED PASSWORD VAULT

Store your passwords in a secure vault protected by AES-256-GCM encryption and biometric lock. Organize entries by category: Social, Finance, Work, Email, and Shopping. Each entry supports a title, username, password, and notes. Your vault never leaves your phone. Export an encrypted backup and restore it on any device.

— STRONG PASSWORD GENERATOR

Generate strong, random passwords in one tap. Control length, uppercase, lowercase, numbers, symbols, and brackets. Advanced options let you exclude similar characters, avoid repeating characters, guarantee character types, and add custom include or exclude lists. A real-time strength meter scores each password as you build it.

— ENCRYPTED BACKUP AND RESTORE
