True Privacy

Security Architecture

We believe your data belongs exclusively to you. Discover how SecurePass utilizes military-grade encryption, local-first storage, and a zero-trust architecture to keep your digital life safe.

Zero-Trust, Local-First Approach

SecurePass has no central database and no backend servers controlling your accounts. Your vault is completely functional offline, meaning there is no centralized honeypot of user data for hackers to target.

Encryption Layer

All sensitive data is secured with AES-256-GCM, a military-grade authenticated encryption algorithm. We use Argon2id for secure password-based key derivation, making brute-force attacks computationally infeasible.

Storage Layer

Your local database is encrypted using SQLCipher. Files and documents are individually encrypted before touching disk. Master keys and biometric keys are secured within the device's native KeyStore/Keychain.

Authentication Layer

A single Master Password encrypts and decrypts your entire vault. Your master password is never stored (only a hash is kept for verification). Quick unlock is supported via secure biometric authentication (Face ID / Fingerprint). We also enforce an auto-lock upon inactivity.

Encrypted Backup & Sync

While SecurePass operates offline, you can enable seamless syncing to your personal Google Drive or export encrypted backups locally.

  • Conflict Resolution strategy guarantees safety per sync.
  • Vault architecture leaves the app entirely Cloud Independent.
  • Files are encrypted before leaving your device; nobody else can read them.
