Beginner’s Summary: Getting Started with Google Authenticator Alternatives
New to two-factor authentication (2FA: a security step needing a code plus your password)? Don’t worry—I’ve got you covered. 2FA adds a second layer of security to your accounts (like email or banking) by requiring a unique code from an app, in addition to your password.
Think of it as a digital key that changes every 30 seconds using TOTP (time-based one-time password: a code generated from the time and a secret key), keeping hackers out even if they steal your password.
Google Authenticator is a popular 2FA app, but it’s basic—it doesn’t sync codes across devices or offer easy backups, which can lock you out if you lose your phone, especially with risks like SIM swap attacks (when hackers hijack your phone number).
In 2025, better options exist for beginners. The apps I’ll cover (like Authy or Microsoft Authenticator) are free, user-friendly, and secure, with features like backups using E2EE (end-to-end encryption: only you can access your data) to recover your codes and simple setups using QR scans (scanning a square barcode with your phone’s camera).
For non-techies, prioritize apps with clear interfaces and tutorials—think 2FAS for simplicity or Proton Authenticator for privacy without complexity.
Below, I’ll break down each app with pros, cons, and my take as a tech pro, so you can pick one that fits your life, whether you’re securing social media or online shopping. Start with one app, test it on a single account, and you’ll be safer in no time.

Below is a detailed, step-by-step guide to ensure a smooth transition without risking account lockouts, based on extensive testing across platforms like Authy, Proton Authenticator, and Aegis.
Step 1: Plan and Prepare Your Migration
Before starting, identify all services using Google Authenticator (e.g., email, banking, crypto wallets). Check if each service supports re-enabling 2FA or exporting keys—most modern platforms do.
Gather backup codes from each service’s security settings and store them securely (preferably in a password manager like 1Password). Use a secondary device or a secure environment (like a laptop) to test logins during migration to avoid disruptions.
Ensure your new authenticator app is installed and ready—popular choices like Authy or Microsoft Authenticator are available on iOS, Android, or desktop.
Step 2: Export Tokens from Google Authenticator
Since 2023, Google Authenticator has included an export feature to simplify migrations. Open the app, tap the three-dot menu, and select “Transfer accounts.” Choose “Export accounts,” select the accounts to transfer, and generate a QR code bundle (split into multiple QRs for many accounts).
Take screenshots or save these QRs securely on an encrypted drive—avoid cloud uploads unless encrypted. For apps like Aegis or 2FAS, scan these QRs directly to import tokens. If a service doesn’t support QR exports, you’ll need to manually disable and re-enable 2FA later.
Step 3: Import Tokens to the New App
In your chosen alternative (e.g., Proton Authenticator, Bitwarden), open the import feature—often under “Settings” or “Add Account.” Scan the Google Authenticator QR bundle to transfer tokens instantly.
For apps like Authy, ensure multi-device sync is enabled before importing to avoid re-scanning on other devices. Verify each imported account by generating a code and testing it on the respective service.
For manual transfers (e.g., services without QR support), log into each account, disable 2FA, re-enable it to get a new QR or key, and add it to the new app.
Step 4: Batch Process and Test in Phases
To prevent errors, migrate in batches of 5-10 accounts. Start with less critical services (e.g., social media) before tackling high-stakes ones like banking or crypto wallets. After each batch, log in/out on all devices to confirm codes work.
If a code fails, re-scan the QR or re-enable 2FA for that service. For apps like Ente Auth, enable encrypted backups immediately after each batch to secure tokens. Keep Google Authenticator installed until all accounts are verified to avoid lockouts.
Step 5: Secure and Finalize the Transition
Once all accounts are migrated, enable app-specific security features like biometric locks (available in Microsoft Authenticator) or PINs (Authy). For open-source apps like Aegis, export encrypted vaults to a secure location (e.g., USB drive).
Delete Google Authenticator’s data only after confirming all services work with the new app. Update backup codes for each service and store them offline or in a password manager. If using cloud-based apps like Proton, ensure E2EE sync is active to protect tokens across devices.
Pro Tips for a Flawless Migration
- Avoid Cloud Risks: If Google Authenticator’s cloud backup is enabled (green cloud icon), disable it after exporting to prevent unencrypted exposure. Apps like Proton or Ente offer E2EE alternatives.
- Use a Migration Wizard: Bitwarden’s January 2025 update added import wizards for seamless QR transfers, reducing manual effort.
- Test Offline Access: For apps like 2FAS or Authy, verify offline code generation for travel or low-signal scenarios.
- Check Compatibility: Some legacy services may require manual key entry—Bitwarden Authenticator allows seed storage for such cases.
- Time Sync: Ensure your device’s clock is synced (Settings > Date & Time > Automatic) to avoid invalid codes.
This methodical approach minimizes risks and ensures your 2FA setup is robust in 2025’s threat landscape, where SIM swaps and phishing are surging.
