Proton Authenticator for PC

Proton Authenticator for PC is a secure two-factor authentication app designed for users who want stronger account protection without depending only on SMS codes or email verification.



It generates time-based one-time passwords directly on your Windows computer, helping you log in safely to supported websites, apps, and online services.

The app is built around privacy, simplicity, and control. It is open source, free to use, ad-free, and designed with end-to-end encrypted sync and backup support when used with a Proton Account.

A Proton Account is not required for basic use, which makes it a practical choice for users who simply want a standalone desktop authenticator.

Proton Authenticator is available for Windows, macOS, Linux, Android, and iOS.

For Windows PC users, the biggest advantage is convenience. Instead of reaching for a phone every time a 2FA code is needed, users can manage and access their authentication codes directly from the desktop.



The FileHorse review team recommends Proton Authenticator Desktop for users who want a clean, privacy-first 2FA tool with strong cross-platform support.
