Trust Through
Transparency.
We believe that security thrives in the open. Our architecture is built on the principle of minimizing cloud exposure, ensuring that your credentials remain encrypted and isolated on your local device.
What ZeroAuth Does
- Enforces local-first data isolation on your hardware
- Utilizes AES-256-GCM authenticated encryption standard
- Leverages OS secure enclaves & fingerprint/face verification
- Functions completely offline without third-party network pings
What ZeroAuth Avoids
- Mandatory cloud sync that exposes key materials
- Storing telemetry, trackers, or plaintext device logs
- Transmitting account passwords or 2FA seeds online
- Implementing custom/proprietary cryptographic libraries
No Server-Side Storage
We operate on a strict "Local-only" boundary. ZeroAuth does not transmit, synchronize, or store your passwords, account credentials, or 2FA seeds on our servers. Your security keys never leave your phone unless you explicitly initiate an encrypted backup export.
Our Security Philosophy
Minimize Attack Surface
Eliminate unnecessary features, telemetry, and background processes to reduce exploit vectors.
Local-First Architecture
Keys, seeds, and metadata are generated and encrypted locally on the device before any other action.
Offline Survivability
ZeroAuth operates at 100% functionality without a network connection. No cloud lock-in.
Reduce Cloud Exposure
Cloud services are treated as untrusted transport mechanisms, never as central authorities.
Transparency Over Claims
We publish our threat models and architectural limits rather than hiding behind marketing.
Defense-In-Depth Mindset
OS-level sandboxing, strong authenticated encryption, and biometric gates are layered together.
How ZeroAuth Works
Our architecture ensures that your credential seeds never touch the cloud in plaintext. Every action is designed around strict local-first isolation and cryptographic boundaries.
Scan QR / Import
Securely scan 2FA QR codes or import passkeys on-device. Seed parameters are parsed directly in RAM, with zero external network requests or logging.
Core Pillars
PIN-First Access Control
The primary layer of defense for your vault is a secure local PIN. Even if your phone is unlocked and handed to someone else, your 2FA codes and passwords remain protected.
Hardware Enclave Isolation
Your decryption keys reside within the secure hardware enclave (iOS Keychain / Android Keystore) on your device. They are physically isolated from standard app storage.
Optional Biometric Shield
Unlock your vault instantly using Face ID, Touch ID, or fingerprint authentication. Biometrics act as a cryptographic shortcut that triggers key access securely.
AES-256 Offline Backups
Export your data as a backup file symmetrically encrypted with AES-256. The encryption process occurs entirely offline, using a strong master passphrase of your choosing.
