PROTON LAUNCHES FREE STANDALONE CROSS-PLATFORM AUTHENTICATOR APP

Summary from the TLDR InfoSec newsletter

Proton Authenticator is a free standalone 2FA app for Windows, macOS, Linux, Android, and iOS that doesn't require an account and features end-to-end encryption with cross-device syncing. The app supports easy import/export functions for TOTP seeds (including from Google Authenticator), automatic encrypted backups, and biometric/PIN locking.  Unlike competing apps, it operates without ads, trackers, or vendor lock-in. The source code will be released on GitHub within weeks.
