Proton is excited to announce a new app that makes everyone’s online security more robust with two-factor authentication (2FA). This corporation is famous for its extreme devotion to privacy and security. Proton Authenticator is free and available for download now. It’s unique for being cross-platform, running on iOS, Android, Windows, macOS and Linux. This launch comes on the heels of the unveiling of Lumo. Proton Chat is the first privacy-respecting use case of this type, but it doesn’t store conversations or train its models using users’ chat data.
Two-factor authentication is now an indispensable security layer not just for security-conscious internet users, but for all internet users. It adds another layer of security on top of password-based login methods. The problem SMS-based 2FA methods, however, are frequently subject to SIM swapping attacks, which enable attackers to hijack a target’s calls and messages. Proton Authenticator is designed to overcome these vulnerabilities by providing an entirely secure alternative.
Eamonn Maguire, Proton’s chief government affairs officer, urged the need for strong security standards.
“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
The app’s launch comes at a critical moment as fears about online safety are increasingly on the rise. Proton Authenticator works in the background to protect your accounts from intruders. This dramatically decreases the likelihood of account takeovers.

“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,” – Eamonn Maguire
