The Password Security Crisis

Current Threat Landscape

The digital security environment has never been more hostile:

Why "Zero-Knowledge" Cloud Encryption Isn't Enough

Cloud-based password managers like LastPass, 1Password, and Bitwarden employ zero-knowledge encryption—they encrypt your passwords on your device before uploading them to their servers, ensuring the company itself cannot decrypt your data.

The Critical Flaw: Offline Brute-Force Attacks

Zero-knowledge encryption protects data while it's on the server. But it cannot protect against theft of the server's contents.

When attackers breach a cloud password manager and steal encrypted vaults, they gain two devastating advantages:

The Lesson: Even the strongest cryptographic algorithms are only as strong as the master password when attackers have offline access to encrypted data.

PassVult's Security Architecture

PassVult solves the offline attack problem through architectural elimination: we don't defend against vault theft—we make vault theft impossible.

Five Layers of Security

Layer 1 Device-Only Storage

Implementation: All password data is encrypted and stored exclusively on your physical device using industry-standard local database technology.

Security Benefit: Eliminates remote attack surface entirely. Attackers would need physical access to each individual device to attempt compromise.

Attack Scenario	Cloud Password Manager	PassVult
Remote server breach	✗ Encrypted vaults stolen from millions	✓ Zero impact—no data on servers
Offline brute-force	✗ Attackers crack weak passwords over time	✓ Impossible—no vaults to steal
Mass credential theft	✗ Single breach affects millions	✓ Impossible—each device separately secured
Cloud misconfiguration	✗ S3 buckets, API vulnerabilities expose data	✓ Impossible—no cloud infrastructure

Layer 2 Military-Grade AES-256 Encryption

Implementation: All sensitive data is encrypted using AES-256—the Advanced Encryption Standard with 256-bit keys used by governments worldwide to protect TOP SECRET information.

Even if an attacker gains physical device access, data remains cryptographically protected without the master password.

Layer 3 Hardware-Backed Key Protection

PassVult leverages platform-specific hardware security to protect encryption keys:

Security Impact: Encryption keys are physically isolated from the main processor and application memory, preventing extraction via malware, memory dumps, or reverse engineering.

Layer 4 Integrated Multi-Factor Authentication

Built-in TOTP Generator: PassVult includes Time-based One-Time Password (TOTP) generation, eliminating the need for separate authenticator apps like Google Authenticator.

Security Benefits:

• Offline operation using device clock—no internet required
• Time-limited validity (30 seconds) minimizes replay attacks
• No third-party cloud dependencies

Layer 5 Travel Mode Protection

Feature: PassVult's Travel Mode provides timed vault locking that prevents access for user-specified durations with no remote unlock mechanism.

How It Works:

1. Before travel, enable Travel Mode and select lock duration (24 hours, 72 hours, one week)
2. Vault locks using time-based encryption
3. No remote override exists—PassVult has no server infrastructure to remotely disable Travel Mode
4. Vault automatically unlocks when timer expires

Use Cases:

• International border crossings where device inspection is common
• High-risk travel areas where device theft is elevated
• Business travel protecting corporate credentials
• Hotel security and public transportation

Frequently Asked Questions

Security Transparency

What We Collect: Nothing

PassVult collects zero user data:

• ✗ No passwords or encrypted vaults
• ✗ No usage analytics
• ✗ No IP addresses or location data
• ✗ No email addresses or personal information
• ✗ No crash reports or diagnostics

Why? We have no servers to collect data on. Your vault exists only on your device.

What We Know: Nothing

PassVult cannot answer questions like:

• "How many passwords does this user have?"
• "When did this user last log in?"
• "What websites is this user storing credentials for?"
• "Has this user's vault been accessed recently?"

Why? This information exists only on your device. We have no visibility.

Compliance & Privacy

Getting Started with PassVult

Setup (2 Minutes)

1. Download PassVult from App Store or Google Play
2. Create strong master password (this cannot be reset—choose wisely)
3. Enable biometric unlock (Face ID, Touch ID, fingerprint)
4. Start adding passwords, credit cards, and secure notes

Best Practices

The Future of Password Security

The LastPass breach was a watershed moment demonstrating that zero-knowledge encryption, despite being cryptographically sound, contains an architectural vulnerability: mass vault theft enables patient offline cracking.

As computing power increases, offline brute-force attacks will only become more powerful. Cloud password managers will respond with higher iteration counts and longer keys—but they're still defending the same centralized servers.
