Show HN: Desktop‑2FA – offline, encrypted 2FA authenticator for your desktop
wrogistefan Sunday, December 28, 2025
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.
Summary
The article discusses a desktop-based Two-Factor Authentication (2FA) application that provides an additional layer of security for user accounts. The app generates time-based one-time passwords (TOTP) and can be used with various online services that support 2FA.
