Technical answers to common questions about our local-first architecture, device security assumptions, and cryptographic tradeoffs.

01. Local Architecture & OS Trust

OS Sandbox

Local Architecture

Technical answers regarding local-first execution boundaries, operating system sandbox integrations, and biometric data handling.

No. ZeroAuth is an offline-capable, local-first authenticator. The cryptographic vault is stored locally on your device, meaning you can generate TOTP codes, use passkeys, and view credentials without any network connectivity. This eliminates the risk of network-based tracking and prevents authentication failures during server outages.

02. Vault Encryption & Backups

Vault Safety
