Proton introduces Proton Authenticator, an open‑source, ad‑free 2FA app with encrypted backup and cross‑device sync for major platforms.
Starting today, the free application is accessible on all platforms, including iOS, Android, Windows, macOS, and Linux. The application enables users to synchronize credentials and accounts across multiple devices.
Like its other products, Proton Authenticator is open source and employs end-to-end encryption to safeguard user data, according to the company.
The company stated that users can integrate login codes from other authentication applications effortlessly—additionally, the application functions without an internet connection and automatically stores credentials.
“Two-factor authentication is indispensable for all individuals, not merely those who prioritize their privacy.”
Eamonn Maguire, Head of Account Security at Proton, stated that Proton Authenticator is designed for individuals who desire a secure, transparent, and user-friendly method of safeguarding their accounts.
“Protecting your privacy and convenience should never be sacrificed to achieve robust security.” This is the reason we created Proton Authenticator: to provide users with the assurance that their 2FA codes are accessible at all times, without the need to depend on Google or Microsoft.
He stated, “We ensure that users have complete control over their data and how they access their online accounts.”
An additional layer of security is provided to users by two-factor authentication, which is implemented through an application, to prevent assailants from gaining access to their accounts.
Although SMS-based two-factor authentication is an alternative, it is frequently susceptible to SIM swapping attacks, which allow attackers to intercept the messages and calls you send.
Proton is currently experiencing an unprecedented surge in product releases. Earlier this week, the organization introduced Lumo, an AI chatbot that prioritizes privacy. Lumo does not retain conversation recordings or utilize user data to train models.
