I’ve released desktop‑2fa v0.4.0 — an offline, encrypted TOTP authenticator designed for desktops, VMs, and air‑gapped environments.

Features: - AES‑GCM encrypted vault with Argon2 key derivation - No cloud, no phone, no telemetry - RFC‑compliant TOTP (SHA1/SHA256/SHA512) - Full CLI (add/list/generate/rename/remove/export/import/backup) - 99% test coverage - Zero external dependencies

GitHub: https://github.com/wrogistefan/desktop-2fa

I built this because I needed a reproducible, open-source 2FA tool for secure workstations and virtualized environments. Feedback welcome.
