WinAuth for Windows

Quick summary of the app

WinAuth is a lightweight, portable authenticator for Windows that provides both counter-based and time-based one-time passwords. It supports standard RFC algorithms for HOTP and TOTP, making it interoperable with many common token implementations such as Google Authenticator. Because it’s portable, you can run it from removable media without installing it on the host machine — a convenient option for users who move between systems.

Main capabilities

• Generates one-time codes using either counter (HOTP) or clock-based (TOTP) schemes in line with the relevant RFC specifications.
• Operates without installation, allowing execution directly from USB drives or other portable storage.
• Works with standard authenticator token formats so entries can be shared or migrated between compatible apps.

Platforms and services supported

• Steam account two-factor protection and similar gaming platforms.
• Guild Wars 2 and other individual game services that accept standard TOTP/HOTP tokens.
• Titles on Battle.net, including well-known games such as World of Warcraft and Hearthstone.
• Cryptocurrency trading sites and other financial platforms that support third-party authenticators.

Why use WinAuth

WinAuth centralizes two-factor codes for many services, reducing the need to maintain multiple mobile authenticators while preserving security. Its portability is especially useful for traders, gamers, and users who prefer not to install software on every machine they use.
