User Reviews

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).

Recent reviews

I have seen another comment on this review page talking about this same design flaw. I would feel a lot more comfortable if I knew that accidentally swiping away an authentication code is not possible. Please fix this in the next update, there is no reason to keep this ‘feature’
