AuthWin review
A focused Windows authenticator with encrypted local storage and no device sync.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AuthWin is a free Windows desktop authenticator for people who want to generate time-based one-time passwords on a computer instead of a mobile device. It supports Google Authenticator imports, QR-code enrollment and manual entry of secret codes. The app keeps account data locally in an AES-256-encrypted file, giving its workflow a clear local-storage focus rather than a cloud-based account model.
Its strongest fit is for Windows users who want a straightforward TOTP tool with several account-transfer options. Individual accounts can be exported as QR codes, while all accounts can be exported as a JSON file. Exported account files can also be protected with a password. These features make AuthWin practical for moving or preserving account information, while keeping the core account data on the Windows computer.
The trade-off is narrow platform and device coverage. AuthWin is Windows-only and does not provide multi-device synchronization, so it is less suitable for people who need the same authenticator accounts available across computers or mobile devices. Its free pricing and local encrypted storage make it a focused choice for a single Windows environment, particularly when cloud storage is not part of the desired workflow. Choose AuthWin if local storage, TOTP generation and flexible enrollment matter most; choose an alternative if cross-device access or broader platform support is essential.
