World's first 100% offline sovereign password manager • Zero Trust, Zero Knowledge

« The world's first password manager that works 100% offline and manages private OTP (TOTP/HOTP) keys with real-time autofill »

Executive Summary

PassCypher HSM PGP is the world's first password manager that works 100% offline and manages private OTP (TOTP/HOTP) keys with real-time autofill — without any server, cloud, or database. Invented and patented in France, developed in Andorra by Freemindtronic, it offers unmatched protection against phishing and typosquatting through sandboxed URL verification and segmented AES-256 encryption. Whether you're in defense, critical infrastructure, or simply want sovereign digital privacy, PassCypher HSM PGP delivers zero-trust security with zero compromise.

New Feature — Passwordless OTP Manager with Anti-Typosquatting Protection

This passwordless manager integrates a real-time TOTP/HOTP key manager. When a TOTP or PIN code field is detected on a web page, the system automatically retrieves and injects the correct one-time code — eliminating any manual steps and ensuring seamless login. This process is safeguarded by the sandbox mechanism embedded in each encrypted container, which verifies the active URL against the original encrypted URL. If a mismatch is detected, the code is not injected — effectively neutralizing typosquatting and phishing threats.

DEF CON 33 — Password Manager and Passkey Vulnerabilities

At DEF CON 33 (August 2025), researchers revealed critical flaws: WebAuthn interception (synced passkeys phishable via spoofed prompts) and DOM clickjacking (11 password managers vulnerable to credential, TOTP and passkey exfiltration). PassCypher HSM PGP eliminates these vectors by Zero-DOM design — no secrets transit through the DOM, no spoofable prompt, no cloud.

The 3 Sovereign MFA Modes

• 1-step authentication: login + password
• 2-step authentication: 1^st (login + password) + 2^nd (injected OTP PIN)
• 3-step authentication: 1^st (login) + 2^nd (password) + 3^rd (injected OTP PIN)

Why Sovereign Architecture Still Matters

While many password managers claim to offer privacy and security, their architectures remain fundamentally dependent on centralized services, external legal jurisdictions, and cloud infrastructures — exposing users, even in Europe, to legal and technical vulnerabilities that contradict Zero Trust principles.

Legal and Technical Independence

Unlike traditional managers that still rely on master passwords, cloud synchronization, or identity providers, PassCypher HSM PGP offers full legal and technical independence. It is natively immune to extraterritorial laws such as the CLOUD Act, FISA, and equivalent frameworks — ensuring unparalleled protection in air-gapped, Zero Trust, or military-grade environments.

International patent coverage: France, European Union, United States, United Kingdom, Japan, South Korea, and China.

Comparison with Cloud-Based Password Managers

Use Cases

Benefits

• Enhanced security: Eliminate common attack surfaces with a serverless, database-free, and fully offline architecture.
• User anonymity: Maintain complete anonymity using zero-trust and zero-knowledge principles — no accounts, no identifiers, no tracking.
• Productivity boost: Automate secure logins in under a second with one-click access.
• Effortless deployment: Set up in minutes without a master password, cloud services, or third-party authentication.
• Built-in OTP (2FA) manager: Automatically handles TOTP and HOTP keys, generates secure PIN codes, and fills them in real time — only if the sandboxed URL matches.
• Military-grade sovereignty: Operates entirely offline, compliant with air-gapped environments and sensitive operational contexts.

Technical Specifications

• Encryption: AES-256 CBC PGP with segmented key architecture
• Auto encryption: Real-time AES-256 CBC encryption on container creation (URL, credentials, OTP keys)
• Storage flexibility: Local disk, removable drives, NFC HSM, or cloud (encrypted)
• Compatibility: Windows, macOS (Chromium-based browsers)
• Browser integration: Extensions for Chrome and Edge
