## Review summary

Proton Authenticator is praised for its clean UI, strong cross-device support, and privacy focus, with easy Google Authenticator import and solid 2FA functionality. However, multiple reviews cite reliability issues: codes disappearing across devices, syncing glitches, and accidental deletions. Backup and storage options have become unstable (Proton Drive and iCloud changes), and import/export reliability varies (BitWarden failures, duplicates). Overall, it’s a user-friendly, privacy-conscious 2FA tool, but data loss risks and evolving backup options are notable concerns.

### Pros

- Clean, minimal UI that's easy to use and not cluttered.
- Cross-device and desktop syncing across iOS/macOS and other platforms.
- Privacy-focused, ad-free, and aligned with Proton's ecosystem.
- Easy import from Google Authenticator and straightforward export/backup options.
- Generally reliable for everyday 2FA with a modern, polished design.

### Cons

- Codes disappearing or being deleted across devices, causing frequent re-imports.
- Sync issues across devices (e.g., entries not editable after QR, codes shuffle when syncing).
- Risk of accidental deletion of entries and lack of deletion-confirmation safeguards.
- Backup/storage integration changes create unreliable backups (Proton Drive backup limitations and iCloud sync removal).
- Import/export robustness problems (BitWarden import failures, duplicates, and limited/export-averse options).
