Free Download Proton Authenticator for Windows PC. It is a simple and secure tool that provides two-factor authentication (2FA) codes to help protect your online accounts.

Overview of Proton Authenticator

This application is designed to add an extra layer of security on top of your passwords. It generates one-time codes directly on your device, making it much harder for intruders to gain access even if they somehow know your password. Unlike other apps, this one is built with user privacy in mind — it’s free from ads, trackers, and unnecessary data collection.

Key Features

How It Works

The tool functions by generating time-based one-time passwords (TOTPs). When you link it with your online account, it creates a constantly changing six-digit code.
