Proton Authenticator – Secure 2FA

Secure passwords are the first layer of security for your online accounts, but they’re not enough on their own to keep you safe from data leaks and hackers.

That’s where your 2FA app comes in. Two-factor authentication adds a second layer of defense when logging in to your accounts. It’s a universally recommended way to keep your accounts secure.

Today we’re introducing Proton Authenticator, a free 2FA app that gives you more flexibility than other authenticators, along with strong encryption from a trusted team. Proton Authenticator is open source like all our apps, available for every device (including desktop!), and lets you import all your existing 2FA tokens in seconds.

Another excellent app from the Proton developers, and you don’t even have to be a subscriber to use the app. It’s free, open source, secure, and cross-platform (yes, that even means Linux).

Check it out  and give it a shot.
