Zero-Knowledge Browser Password Manager With Hardware Enclaves

C6/10May 4, 2026

WhatA cross-browser password manager that leverages hardware security modules (TPM/secure enclave) on the device to ensure credentials are never in plaintext in general-purpose RAM, even while autofilling.

SignalMultiple commenters noted that every browser — not just Edge — keeps passwords in cleartext in memory, and that even dedicated managers like KeePass have acknowledged similar memory exposure windows, suggesting users who care about security have no truly hardened option today.

Why NowTPM 2.0 is now mandatory on Windows 11 machines and Apple's Secure Enclave is universal on Mac/iOS, meaning the hardware to do this properly is finally ubiquitous in the install base.

MarketSecurity-conscious consumers and enterprise users; password manager market is ~$2B growing 15%+ annually; Bitwarden and 1Password dominate but neither leverages hardware enclaves for in-memory protection.

MoatHardware-level integration with TPM/Secure Enclave across platforms creates a deep technical moat and makes the product meaningfully more secure than software-only alternatives — hard for incumbents to retrofit.
