Best authenticator app
After making the switch from Google Authenticator, I have no idea why I tolerated Google for so long. Proton works well, it respects your privacy, and has better features and design. Major bonus points for having a desktop app too. I really hope Proton continues to support Authenticator long into the future. Small complaint: shorten the app name under the app icon. Just call it “Proton Auth” so that the name isn’t truncated and displayed with an ellipsis. It just looks like poor execution, which doesn’t inspire confidence in a security app.
always server error
not good, uninstalled.
Code Accidental Deletion
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’
Needs work
I like you can sync between devices with your Proton account but every time you open the app your 2fa accounts have changed position...tried on 2 different iPhones different models and 2 different iPads and those were also 2 different models and the 2fa accounts change position every single time. Ente and 2FAS are my number 1 and 2 with Proton in last place until they get their finger out! I can reproduce this time after time constantly changing positions each time I open the app...on the other Ente and 2FAS never change the position of your accounts. Tried on 2 different models of iPhone and 2 different models of iPad
Issues with syncing authentication apps between iPad and iPhone
Unable to sync
It works
Ability for local backups is great!
Stopped working
Stopped working with newest updates everything is crashing
Finally a clean authenticator app that doesn’t feel shady
I'd say this app deserves four stars overall. It handles the main stuff pretty solidly, and its cleaner than most security apps out there. You open it quick when you need a code, and everything looks straightforward without all the junk. No weird ads popping up or pushes to buy something extra, which is nice for a 2FA tool like this. The privacy side stands out too, especially since it’s free. That makes me more likely to suggest it to people. I think thats the part that gets it points over some others. But yeah, it doesnt quite hit five for me because it still comes off as kind of new. With these authenticator things, I worry more about trusting it long term rather than just the basic idea. Ive only used it a bit, so Im not ready to say its perfect yet. If youre already set up with something like Apple Passwords that works right into your phone, switching might not even cross your mind. Stability matters a ton here, since even tiny glitches could mess up access to accounts. Proton has patched some starting bugs, which shows they care, but it also reminds me the apps still growing up. I might be oversimplifying, but that maturing process feels real. I plan to stick with it myself, mainly because its simple and privacy oriented without any ad nonsense. It seems solid enough for now, though not totally flawless. Close to being really great, I guess.
Not working for importing google authenticator
Unfortunately not working for importing Google authenticator codes: menu drops out after hitting import and- nothing! App looks and feels lovely to use but I just wish the import from this particular other authenticator would work seamlessly!
Backup issues
This morning I got this message when using the app “iCloud backup is no longer available- Your 2FA codes are safe. Due to reliability issues with Apple's iCloud, we've switched to the new backup - works with any drive app including Proton Drive, Dropbox, iCloud and more”. It would appear from my settings it’s no longer backing up to iCloud. The message however suggests iCloud is still an option. A circular message, it would seem. Needs work.
MacOS Experience
Works very well on MacOS Desktop, Best 2FA Authenticator ever🥰
no code is working
after the last update none of the codes work anymore
Works pretty well but has some bugs on iOS
Works pretty well, but one of the more annoying bugs is if you have device sync on it “shuffles around” your codes whenever you open the app. If you have the desktop app and you organize your codes there, the phone will reflect it properly next time you close and reopen it.
Schlechte Performance
Die Performance der App ist einfach echt schlecht. Scrollen tut in den Augen weh. Ich hatte auf ein Update gehofft, aber jetzt wird die App ersetzt. Schade, denn die Funkion den nächsten Code bereits angezeigt zu bekommen ist simpel aber nützlich.
Neat Implementation, but redundant
This is a neat tool, but I would much prefer to have an Authenticator tab built into Proton Pass
UI Design
I just miss the grainy/noisy grey background UI design, it was removed 😢
Can't backup codes to Proton Drive
The latest release says you have the ability to backup your codes to Proton Drive. However the last release of proton drive removes it from the Files app. There is no way to set your codes to backup on Proton Drive.
Good but with serious flaw
This is a really nice Authenticator app, especially since it can sync with a desktop version in multiple ways. Not many Authenticators do that. The problem with this Authenticator is that it is too easy accidentally delete an account from your list with an accidental swipe. There is no need to for such a simple method of deletion on an Authenticator. It is not like you delete multiple items per day like email. The delete function should be very deliberate and have a confirmation step. Fix that and this would be about the best Authenticator currently available.
appalling system performance
As much as I love Proton’s other products (seriously top tier VPN and Mail services), trying to scroll through the list of codes stutters the whole app (M1 MacBook Air). There’s more than enough power on this system to scroll through some text and images. Back to ente auth I go then.
Removed iCloud sync
This app was amazing, but they removed free iCloud syncing which automatically kept all my codes up to date across all my devices (including Windows with iCloud installed). Sorry, I don’t want to have to trust Proton with all my security codes by creating an account there. (And, yes, Proton Authenticator is open source, but there’s no way to verify the open source code was used to build this app.)
Update review
Search function was not working. Now it is back to normal. I can easily search the proper account. Very helpful when you have dozens of accounts.
What have you done!!!
Removed iCloud backup which has always worked for me and replaced it with something that does not work! I switch on Auto Backup and it asks for a password, that’s understandable. However, after you save you password, you are simply thrown into Apples File app in its recent folder with no file there yo save or check.
Slightly laggy
Works like a charm, though the UI feels a little laggy when scrolling on iPad compared to 2FAS. Also lacks a way to modify the logo.
Very bad UX
Swipe to delete a code is an absolutely wild decision. Can’t believe someone actually signed off on that. Good luck to anyone who accidentally swipes on a code. Huge security issue that falls short of Proton’s usually high standard.
App name cut off
Would love if the app name wasn’t “ProtonAuthentic…” on the Home Screen
Best Authenticator App
This has been the best Authenticator app that I’ve personally used (and I’ve used several). Works very well for everything you can ask for with this kind of app and I love the peace of mind it brings with knowing they’re not harvesting unnecessary personal data. I’m not a fan of the fact that the encryption keys for windows OS desktop app is stored locally…defeats the purpose in my eyes for privacy and security, hoping that’s updated in the future. I also am hopeful for it to fully integrate/sync with proton pass eventually if you choose to opt into that. I’d recommend the use of this app to anyone.
Bug with biometric lock
Select "Biometric lock" in the settings. Now when you open the app on a device which requires touch ID (iPad Air M3) you need to touch the sensor on the device in order to open the app. However, if your finger(s) you use for authentication is injured, or you select "Cancel" in the touch ID popup, you will not be able to use the app any more. The touch ID popup will keep coming up and it will never be dismissed. As a result, you can't even swipe the app to the background, which will render you entire device unusable unless you shut it down. Normally if touch ID fails the third time, the system presents entering your device code. But this option is not presented if touch ID fails, so you are cooked. This is stupid. In order to have biometrics enabled on your device, you have to have a code as well. So why lock people out of the app and their device if touch ID fails, and in those cases just present the code entry option.
Looks nice but a couple of functional flaws
Update: Now supports various sorting options. Nice. +1 star The interface looks decent; import worked well; synching is working; BUT import created a few duplicates (not present in the source data); therefore there is no duplicate detection: and the display is ordered by time created, apparently—no way to sort by account or provider name, which would seem to be a most basic feature. Finally, there is no Export function: what’s labeled “Export” in setting is just a Proton-specific backup file, quite insecure. Room for improvement.
Import issues
Can’t import from BitWarden. Following the instructions to export to json.. at import Error invalid format!?!? Are you kidding me. It’s a JSON file.. how lame from a biga name company..
Needs more refining
The app does more or less what you need & let me get off an alternate product. It would benefit from a few more refinements. Suggestions. - Folders for keys to be grouped. Please. I’d like my work ones in a separate place. Doom scrolling every day. Or could favourites or labels to filter on with. Labels could be better. ? - Manual reorder mode. Not one by one. It takes ages and is difficult to use. Keeps dropping into edit mode. - Compact view by icon screen.
Anything but google.
I refuse to use google anymore. This is a great authenticator app. Proton mail and vpn are also excellent for privacy. Never going back. Beyond sick of the ai.
Feature Failures
Sweet 5 star design, BUT… Want to regenerate and replace your 2FA TOTP code? Sorry, you can add another but cannot remove, the old one. Want to rename the old one to market it deprecated? That doesn’t work either. How does Apple allow this product on their store? ABOUT does not even work.
UI
Needs a way better ui
Does not save codes. BEWARE
I am a huge fan of Proton, and finding out they have an Authenticator I immediately jumped on board. And it would be good: if it actually kept the codes. On all platforms (for me, iOS and Mac) the codes are deleted constantly. Sometimes immediately while in the app, I’ll open the settings page and they’re all gone, as if I had just installed the app. I have to REIMPORT THEM EVERY TIME I need a code. Absurd. Please fix this, luckily I backed the codes up before deleting Google Authenticator, otherwise you would have lost me access to everything. Don’t bother collecting troubleshooting data, happening on multiple platforms means there’s internal problems. Check your code. Well. Very well.
Sufficient
Works for all of your everyday 2FA needs. Missing quality of life features like being able to set icons for each entry or upload custom ones (given that half of my 50 entries are missing one)
Proton Finally Got It Right
I spent a long time looking for a company that could build a secure, easy-to-use authenticator app, and Proton absolutely nailed it. Okta looks polished and offers push notifications like Duo, but switching phones is more of a hassle than it should be. Google Authenticator does not give me the same easy access across all my devices that Proton does, which is a huge advantage for Proton. Apple Passwords is excellent when biometrics are involved and works well for OTPs, but when it comes to accessing and managing OTP codes, Proton Authenticator is simply easier and more convenient to use. It is simple, secure, and straightforward — exactly what I wanted.
Deception in description
In the description it clearly states that it can import from Authy, it’s even in the screenshot artwork, but what the artwork cleverly leaves out is the yellow ! Warning next to Authy.. and when clicked on states it does not import from Authy and to contact the Authy developers about it..??? I think I’m good then, I’ll stick to Authy, as being deceived within a few seconds of using the app ain’t a good look.
Suggestion
App looks nice, good progress. Would prefer the ability to set a different PIN for unlocking the app, similar to what the proton mail app’s ability is.
Outdated Look
I feel like I logged into a 1995 Macintosh layout. It looks terrible. I’ll stick to 2FAS, much better.
Buggy
On iOS the search often ends up stuck on the middle of my screen making only the top half scrollable!
Clean
Cleanest Authenticator app I’ve used. It looks really nice and doesn’t overload you with random options. But why do Proton apps get updates so infrequently? That’s my huge issue with them.
Import is buggy
If, like me, you prefer to keep all your data on device and not sync to any cloud accounts, beware that you will not be able to transfer your codes from an old device to a new device. The export to a file works well, but when importing that file, it will appear to have successfully imported, but as soon as you close the app your newly imported codes will be gone!
Amazing support
Whilst I still think this app needs a little more tweaking I’ve been amazed at the support. I opened a ticket with Proton saying I was having trouble importing batches of accounts from Google Authenticator and it was fixed in under a day. If the other minor problems are fixed as quickly this will be a 5 star app in no time.
Expected Proton quality is way off mark
As an Unlimited subscriber this release falls way short of the expectations. I guess it does the job but the UI is horrible and weirdly misaligned with the rest of Proton’s design language, no encrypted exports, no way of reordering entries (let me do alphabetical!) and no pinning to the top. I’d also like for entries to be waaaay more compact so it fits more in a single screen and it’s easier to read, and to be able to tag entries (see Ente Auth). C’mon, Proton! I’ll revise this review later if things change.
Missing Autofill
It’s missing autofill in iOS so I’m not sure why I’d migrate from another Authenticator or even Proton Pass which supports TOTP token management and autofill.
Simple but effective
It’s nothing fancy, but I am finally able to get rid of Authy for my Proton login. All my other authenticators are just stored in Proton Pass.
Piece of garbage
I switched to this piece of garbage about 6 months ago from Google Authenticator, only to find out that my codes have mysteriously disappeared. When I contacted their Zendesk support, they took a week to respond, only to ask me whether I still needed help. (Zendesk is a lame excuse of support. They are a useless cheap support that doesn’t really provide any real support). Don’t risk your codes with this app!
Can’t login to account using iPad version
Update v1.1.3 - login issue now appears to be resolved for iPad version. Original: A key piece of functionality is the ability to ensure codes are saved and shared between devices. Unfortunately as others have said, this doesn’t work, making this part of the app useless.
Unable to login proton account
I not able to login into my proton account if I have enabled iCloud backup sync
Lots of glitches
Unfortunately, I experience lots of glitches when trying to add codes. I tried migrating from Google Authenticator and it constantly throws an “error with QR code”…
