Securing Your Online Accounts with Authy: Multi-Device Support & Encrypted Backups

29 January 2025

Cybersecurity is now more critical than ever. Protecting your online accounts with two-factor authentication (2FA) adds an extra layer of security against cyber threats. One of the best 2FA apps available is Authy, which not only provides strong authentication but also offers multi-device support and encrypted backups for added convenience and security.

In this guide, we will walk you through the steps to set up Authy and take full advantage of its features.


Why Choose Authy?

Authy stands out from other authentication apps due to its unique features:

  • Multi-Device Support: Access your authentication codes on multiple devices, such as your phone, tablet, and computer.

  • Encrypted Cloud Backups: Never lose access to your accounts by securely backing up your 2FA tokens.

  • Offline Functionality: Works without an internet connection.

  • Secure and User-Friendly: Easy to set up and use, ensuring a smooth experience.

Step-by-Step Guide to Setting Up Authy

Step 1: Download and Install Authy

Authy is available for multiple platforms. You can download it from:

  • Android: Google Play Store

  • iOS: Apple App Store

  • Desktop (Windows, Mac, Linux): Authy Website

Once downloaded, install the app on your preferred device.

Step 2: Register Your Phone Number

  1. Open the Authy app.

  2. Enter your mobile phone number.

  3. Choose whether to receive the verification code via SMS or phone call.

  4. Enter the received code to verify your identity.

Tip: Use your primary phone number to avoid issues when accessing backups or restoring Authy on a new device.

Step 3: Enable Multi-Device Support (Optional)

Authy allows you to access your authentication codes on multiple devices.

  1. Open Authy and navigate to Settings.

  2. Find the Multi-Device option and enable it.

  3. Install Authy on your other devices and sign in using your registered phone number.

Important: If you disable multi-device support later, new devices will not be able to sync with your existing account.

Step 4: Adding Accounts to Authy

To use Authy as your 2FA app for online accounts:

  1. Log into the website or service where you want to enable two-factor authentication (e.g., Google, Facebook, Dropbox, Amazon, or banking apps).

  2. Go to the Security Settings or Account Settings.

  3. Look for the Two-Factor Authentication (2FA) option.

  4. Select Authenticator App as your 2FA method.

  5. A QR code will be displayed on the screen.

  6. Open Authy, tap Add Account, and select Scan QR Code.

  7. Scan the QR code to add the account to Authy.

  8. A six-digit code will now appear for the linked account, refreshing every 30 seconds.

  9. Enter the generated code on the website to complete the setup.

Step 5: Enable Encrypted Cloud Backups

To ensure you don’t lose access to your authentication codes, enable encrypted backups:

  1. Open Authy and navigate to Settings.

  2. Select Accounts and enable Backups.

  3. Set a strong backup password (this is required to restore accounts in the future).

Note: Authy does not store your backup password, so ensure you remember it or store it securely.

Step 6: Secure Your Authy App

For additional security:

  • Enable PIN Protection: In Settings, activate PIN or biometric authentication (fingerprint or facial recognition).

  • Disable Multi-Device Support: If you don’t need it, turning this off prevents unauthorized access.

  • Regularly Update Authy: Keep the app updated to benefit from security improvements.

How to Restore Authy on a New Device

If you lose access to your device or need to set up Authy on a new one:

  1. Download and install Authy on the new device.

  2. Enter your registered phone number.

  3. If you have Multi-Device Support enabled, Authy will sync your accounts.

  4. If you have Backups enabled, enter your backup password to restore accounts.
