Proton has launched a brand-new two-factor authentication app! Called Proton Authenticator, this cross-platform app is designed to give users full control over their 2FA codes without the usual trade-offs like ads, trackers, or vendor lock-in.
These days, just having a strong password isn’t enough. Hackers and data leaks are everywhere, and enabling 2FA is one of the easiest ways to protect your online accounts. While SMS-based 2FA is still common, it’s risky. SIM-swapping attacks can render it useless. A proper authenticator app is far more secure because the codes are generated locally and constantly refresh.

What makes Proton Authenticator stand out is that it’s not just another app slapped together with a pretty UI. It’s free, open source, and works across all major platforms… iOS, Android, macOS, Windows, and yes, Linux too. As someone who uses multiple operating systems, I absolutely love the cross-platform support. And the fact that it doesn’t cost a dime is a huge win for privacy-minded folks who are sick of being tracked or charged just to protect their data. I plan to use this personally going forward.
The app supports encrypted syncing across your devices, but you can also choose to keep everything local if that’s more your style. You can import existing tokens from other apps in seconds and export them just as easily, which is a big deal considering how many authenticator apps try to trap you in their ecosystem. It even works offline and can be protected with a PIN or biometric login.
If you already use Proton Pass, you might be wondering why this app even exists. Well, Proton Authenticator is for people who want a separate, dedicated 2FA app that doesn’t mix your authentication codes with your passwords. Some users prefer that extra layer of separation for better security. Others just like having choices, and that’s exactly what Proton is offering here.
I’ve long respected Proton for putting user privacy first, and this new app is no exception. It’s open source, transparent, and not tied to any creepy data-harvesting schemes. Whether you’re a longtime Proton Mail user or just someone looking for a reliable authenticator, this app deserves your attention.
Proton Authenticator is available now, and it costs nothing. If you’ve been looking for a trustworthy 2FA app that plays nice with all your devices, this is it.
