Could you build this?
No A zero-trust password manager with remote browser isolation for AI agents requires advanced cryptographic engineering, browser extension architecture, and hardened container execution environments.
What it would actually take: This architecture requires zero-knowledge client-side encryption (implementing Argon2id, WebCrypto, and post-quantum algorithms) paired with a scalable remote browser isolation (RBI) infrastructure running headless Chromium instances in microVMs (e.g., Firecracker). The hard engineering problems lie in securely auto-filling credentials into sandboxed cloud sessions without exposing the secret keys to the LLM agent, alongside non-repudiable cryptographic audit logging.
