Privacy-focused productivity tool company Proton released a new authenticator app today, allowing users to log in to services using dynamically generated two-factor authentication codes. The free app is available on all platforms starting today, including iOS, Android, Windows, macOS, and Linux. The app allows users to sync codes and accounts across devices. The company said that just like its other products, Proton Authenticator is open source and uses end-to-end encryption to protect user data. Users can easily import login codes from other authentication apps. Plus, the app automatically backs up codes and also works without any internet connection. “Two-factor authentication is essential for everyone – not just those who care about their privacy. Proton Authenticator is built for anyone who wants a secure, transparent, and convenient way to protect their accounts,” Eamonn Maguire, head of Account Security at Proton, said. “We believe strong security should never come at the cost of your convenience or privacy. That’s why we’ve developed Proton Authenticator: to give users peace of mind that their 2FA codes are available wherever they need them, without relying on Google or Microsoft. We’re putting users firmly in control not only over their data, but the way they access their online accounts,” he added.
