Should you build your own Proton Pass Plus?
Create a local password and alias vault with portable encrypted backup
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Proton Pass Plus, create a local password and alias vault with portable encrypted backup. The hard boundary is proton identity, email alias infrastructure, audits, apps, recovery, and privacy operations, plus security assurance, infrastructure, and trust.
ENOriginal research content in English. Original prompt preserved in English.
Build a closest honest personal substitute for Proton Pass Plus in an empty repository.
Use Rust, Tauri 2, React, SQLite, Argon2id, and audited cryptographic libraries; do not offer alternative stacks.
The core loop is: create a local password and alias vault with strong encryption, portable encrypted backups, explicit threat-model documentation, and no claim of replacing an audited service.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Write a plain-language threat model before implementing any sensitive feature.
Keep all vault data encrypted with a master key derived through Argon2id and a unique salt.
Use authenticated encryption from a maintained library and never invent cryptographic primitives.
Implement lock timeout, clipboard clearing, password generation, import, export, and encrypted backups.
Make recovery-key creation explicit and test restore from a fresh installation.
Display a persistent warning that the build has not received an independent security audit.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out a production VPN or anonymity network.
Deliberately leave out identity-protection monitoring and data-broker removal.
Deliberately leave out enterprise security guarantees, audits, and emergency support.

What would building your own look like?
Create a local password and alias vault with strong encryption, portable encrypted backups, explicit threat-model documentation, and no claim of replacing an audited service.
What you will need
- desktop OS
- secure backup location
- modern cryptographic libraries
- careful review before real-world use
People still pay for Proton Pass Plus because security products are paid for because expert review, infrastructure, and accountability matter more than recreating screens. The recurring cost buys cryptography, secure updates, key recovery, threat intelligence, relay capacity, abuse response, audits, and incident handling, not just the visible interface.
