🧠 Why Use Proton Authenticator?

According to Eamonn Maguire, Head of Account Security at Proton:

“Two-factor authentication is essential for everyone — not just those who care about privacy... Proton Authenticator offers strong security without giving up your privacy or convenience.”

He added that Proton wants users to have full control over how they access and protect their accounts — without relying on Google or Microsoft tools.

⚠️ Why Two-Factor Authentication Matters

Using 2FA helps protect you from hackers who might try to break into your accounts. Here’s why app-based 2FA is better than SMS-based 2FA:

• More secure – Harder for hackers to access

• Prevents SIM-swapping – Attackers can’t intercept your codes through your phone number

🚀 More Proton Tools Coming

This new app comes shortly after Proton released Lumo, a private AI chatbot that doesn’t store your chats or use your data to train models.
