Getting hacked isn’t just about losing a password anymore. A single breach can expose your entire digital life.
Two-factor authentication (2FA) protects you, but most authenticator apps trap your codes on one device, leaving you locked out if your phone breaks or gets stolen.
In this step-by-step tutorial, we’ll show you how to set up Proton Authenticator, the open-source 2FA app that gives you:
🔑 Cross-device sync – access your codes on phone, laptop, and desktop
🔒 End-to-end encryption – no one can access your codes (not even Proton)
☁️ Automatic backups – restore your codes in minutes if you lose your device
📱 Offline access – your codes work even without an internet connection
We’ll walk you through:
✅ Installing Proton Authenticator on all your devices
✅ Importing existing codes from Google Authenticator and others
✅ Creating new 2FA codes for your accounts
✅ Enabling cross-device sync and automatic backups
✅ Securing your codes with biometrics and encryption
Take 15 minutes to set this up now and save yourself days (or weeks) of account recovery later.
