Proton Authenticator

Overview of Proton Authenticator

Proton Authenticator is a privacy-first two-factor authentication (2FA) app that generates secure login codes for your online accounts. It is part of the Two-Factor Auth and Encryption Tool categories on ToolPicker. Built by the team behind Proton Mail, this open-source application provides an extra layer of security beyond passwords, ensuring that even if hackers obtain your credentials, they cannot access your accounts without the time-sensitive codes. The app works completely offline and is available across all platforms – desktop and mobile – making it accessible wherever you need account protection.

Designed for security-conscious individuals and organizations, Proton Authenticator serves as a reliable alternative to popular authenticators like Google Authenticator while offering enhanced privacy features with no ads, no tracking, and fully verifiable code. It supports easy migration from other authentication services and provides flexible backup options to prevent lockouts. As part of the Proton ecosystem, it integrates seamlessly with other privacy-focused tools while remaining fully functional as a standalone application for securing personal and business accounts.
