AuthBox
Offline two-factor authenticator for Windows
AuthBox keeps your two-factor codes and recovery details in an encrypted vault on your own computer. No account, no server, no telemetry — and no way for anyone, including the developer, to read your vault.

What it does
- Generates time-based one-time codes (TOTP) for any account that supports them.
- Stores each account's notes, security questions, recovery keys and backup emails alongside the code, so everything about an account lives in one place.
- Encrypts the whole vault with AES-256-GCM under a key derived from your master password with Argon2id.
- Imports accounts by scanning a QR code shown on your own screen.
- Copies a code to the clipboard from a global keyboard shortcut, without opening the window.
- Corrects a drifting system clock on demand, so codes are not rejected.
- Supports multiple separate profiles, and a portable copy you can carry on a USB drive.
