Master Keys. Beyond Reach.
Cloud password managers concentrate every credential in one always-online target. A Firevault Password Vault keeps your master keys, seed phrases and recovery codes physically disconnected, retrieved only when you authorise it.
Password Vault
Your most sensitive data deserves protection that goes beyond software. Firevault provides the only storage that is physically unreachable by design.

One online vault. One catastrophic blast radius.
Cloud Vault Exposure
Encrypted or not, a cloud password vault is permanently online. When the provider is breached, your entire credential set is exfiltrated in one go.
Master Key Single Point Of Failure
One stolen master password, session token or device unlocks everything. Phishing, malware and SIM-swap attacks all converge on this single key.
Crypto Seed Phrase Theft
Seed phrases stored in notes apps, screenshots or cloud password managers are routinely harvested. Once gone, the funds are gone.
This is already happening to credential vaults.

The Scenario
One vault. Everything gone.
A high-net-worth individual stores their master password and crypto seed phrase in a leading cloud password manager. The provider is breached. Within 72 hours, £2.3M of digital assets are drained and personal accounts compromised across banking, email and identity. With a Firevault Password Vault, those credentials would never have been online to steal.
"If a single password unlocks your entire life, it should not live on the internet."
Store the keys to everything offline.
Your master credentials, seed phrases and recovery codes live inside a physically disconnected vault. They cannot be remotely phished, scraped or exfiltrated, because there is no connection to attack.
- Offline Secure Storage for master passwords and root credentials, offline by default and reachable per session
- Tamper-evident custody for crypto seed phrases and hardware wallet backups
- Offline 2FA backup codes and recovery keys, retrievable on authorised request
- Physical retrieval only, no remote access, ever
Take Credentials Off Connected Password Managers
Step 1 of 3Master credentials, seed phrases, and recovery codes are taken off connected password managers and written to physically disconnected RAID 1 drives inside a Firevault Bunker. No cloud vault. No always-on target.
