Proton has released Proton Authenticator, an independent, standalone 2-factor authentication (2FA) app for macOS, Windows, Android, Linux, and iOS. 2FA verification applications are offline tools that create time-based OTPs that expire within 20 seconds, and can also be used with passwords when signing into offline accounts, offering a second layer of verification.
A Swiss tech company, Proton, is famous for its privacy-focused end-to-end encryption services such as
Integration of an authenticator app adds to the company’s product portfolio and brings a privacy-specialized tool that challenges competitors that are mostly ad-supported, closed-source, and trap customers into proprietary ecosystems.
But Proton Authenticator doesn’t have ads, vendor lock-in, or trackers, and uses no Proton account. According to the company, “Proton Authenticator is built with the same values that power everything Proton does: privacy, transparency, and user-first security.” "The company is now bringing these standards to the 2FA space – offering a secure, easy-to-use, and encrypted alternative to apps like Google Authenticator that further lock users into Big Tech's surveillance ecosystems."
The application is open-source, but it takes around two weeks for the Proton team to release the source code of the latest tools on GitHub. The app has end-to-end encryption, which supports safe cross-device sync and shift to other platforms via easy-to-use import and export features. A lot of apps, such as Microsoft and Authy, cannot export the time-based OTP seeds feature.
The Proton Authenticator also provides automatic encrypted backups and app lock with PIN or biometrics, giving an extra security layer.
“Proton Authenticator will make it easier for everyone to log in to their online accounts securely, a vital step in making the internet a safer place,” read the product statement.
