I would like to propose the development of a Proton hardware password manager, similar in concept to Ledger (used for crypto), but designed specifically for secure credential storage and input, while fully aligned with Proton's privacy principles.

🔐 Core Concept:

A dedicated, tamper-resistant USB hardware device that:

Stores passwords securely offline

Presents a list of stored usernames only to the user

Prompts the user on-device (via a screen + buttons or touchscreen) to select and approve password entry

Emulates a USB keyboard to type the selected password into the target system (not via clipboard or memory injection)

This way, passwords never reside in system memory, avoiding RAM scraping, clipboard attacks, and keylogging risks on compromised devices.
🎯 Key Benefits:

Zero memory footprint on host device—passwords are never exposed to malware or RAM dump tools

Cross-platform & air-gapped-compatible (works on any device with a USB port)

Reduces reliance on autofill, improving both security and transparency

Could integrate with Proton Pass vault syncing (if optional cloud sync is desired)

Appeals to privacy-conscious users, journalists, and enterprise clients with high-risk profiles

💡 Bonus Features (Optional):

PIN or biometric protection for device access

Support for passkeys/FIDO2/WebAuthn in future firmware

Compatibility with open standards (like KeePass vault formats, for user migration)

Open-source firmware (to align with Proton’s transparency ethos)

🙏 Why This Matters:

Memory-resident password exposure remains a known limitation of even the most secure software-based managers—including Proton Pass. This hardware approach offers users the option of full physical control and zero in-RAM exposure, without compromising usability.

I hope this concept aligns with Proton’s mission to bring user-controlled, privacy-focused solutions to life. Thank you for your continued innovation.
