Solid Authenticator with Room to Improve
11/08/2025

MintedFox
Great to see Proton release a proper authenticator app! A few suggestions:- Add native macOS support (currently runs as an iPad app).- Fix cross-device sync login issue — on my MacBook Pro, the screen closes after password entry.- Offer more view options on MacBooks for easier code management beyond the basic list view.

Few of the issues you've mentioned are now addressed in the latest 1.1.3 version of the app, so make sure to update.

Deleting codes from one device doesn’t delete them from Proton service/account and all synced device
14/09/2025

Deleting codes from one device doesn’t delete them from Proton service/account and all synced devices. Please fix this. I have deleted codes multiple time but whenever I login into Proton synced account, all deleted codes come back. Codes once deleted should get permanently deleted from proton account and all synced devices.Reiterating my concerns dated 14th September 2025:There’s a major flaw in Proton’s sync all your devices feature and backup to iCloud. The codes which I delete from one device, whether it’s an Apple device or any other, those codes always come back when I refresh the page. Deleting codes from any synced device should also permanently delete it from proton account as well as iCloud backup. One more thing, Proton needs to provide an option to bulk delete codes. It painfully long process to delete codes one by one. Both these issues are annoying and inefficient. Can’t use Proton Authenticator with these two issues. Other Authenticator apps at least delete codes permanently from derive and cloud even if they have been synced to any cloud storage option.

Pretty good

One or two times the codes generated were not accepted by the service I was trying to log into. Other than this, it has worked well for me. Really appreciate Proton for creating this app and making it cross platform!

Too slow

I really like to use this app as main Authenticator but it’s very slow to load and some times I found timer just stuck.I have premium account but proton pass is too bad to use as it’s not clean in look and experience.I hope this app gets all fix.
