European Alternatives to Google Authenticator
Google's two-factor authentication app. Generates TOTP codes to secure your online accounts.
Google Authenticator Features
- TOTP code generation
- Google cloud sync
- Multi-account support
- QR code for easy setup
- Available on iOS and Android
Why leave Google Authenticator?
- Synced codes are accessible to Google and potentially to US authorities via the CLOUD Act.
- Not open source: code is not publicly available, impossible to verify security practices.
- In 2020, Cerberus malware could extract 2FA codes from Google Authenticator on Android.
- No native export for years, making migration to other apps difficult (added later).
