Unfortunately I only found out after having gone through the hoops to set the whole thing up on my iPad first. Stop forcing us to buy new tech, creating endless ewaste rubbish. iOS 16 is perfectly secure, as evidenced by the fact that Wise bank still happily support it with biometric verification, facial scanning, etc. **Developer response:** Sorry to hear that. The Proton Authenticator app requires iOS 17.0 or later. Nonetheless, we've passed on your feedback to the team accordingly. ### 4/5 — Good for what it is *2026-10-11, version 1.4.4* Always good to see a privacy focused product. Moved away from Microsoft Authenticator a while back, I like this product. My only complaint would be that some 2fa apps don’t allow exports (presumably to keep people trapped to that app) but that’s not your fault so yea. ### 2/5 — Ehh… *2026-09-30, version 1.4.4* I first saw this and was excited because I know proton is private, so i downloaded it and transferred my codes from Google Authenticator (this is an option in the app to import from Google) but when I looked at the codes they were generating different numbers, tried to use one and it didn’t work. Ok I’ll just delete a code and try to re add it in proton “code not supported”. Good idea but doesn’t currently work. ### 4/5 — Good alternative but ugly *2026-09-27* As an Authenticator app it’s completely fine and functional and a great alternative to google Authenticator. But the app itself is not very user friendly or appealing to look at. Which is odd because the other proton services have very good UX. The sync option sometimes is a bit temperamental but has been a bit more stable recently. Overall it’s good but the UX can be improved. **Developer response:** Thank you for the review. We have passed on your feedback to the team accordingly. That said, if you happen to be experiencing any issues with Proton Authenticator, feel free to let us know using the "Feedback" option in the app's settings. We're always happy to help. ### 3/5 — The proton start *2026-09-20* 3/5 **Developer response:** Thank you for your feedback. If you have any suggestions on what we can do to improve, let us know in an update to your review. ### 3/5 — Issues with syncing authentication apps between iPad and iPhone *2026-09-08* Unable to sync **Developer response:** Thank you for the review. Could you share more details about the issue? What are the exact steps you're taking? Are you receiving any error messages? Have you followed the guide on our support page on syncing your 2FA codes? Contact us using the "Feedback" option in the app settings with more details so we can investigate further. ### 5/5 — Einfach und Praktisch *2026-09-03* Macht was er soll. Ich wünsche mir aber, dass neben dem individuellen Namen auch ein Logo / Bild eingetragen werden kann. Das würde die Übersichtlichkeit deutlich verbessern. ### 5/5 — It works *2026-08-31, version 1.4.4* Ability for local backups is great! ### 4/5 — Works but could be better *2026-08-31* Would be awesome if you could create folders. **Developer response:** We've passed your suggestion on to the team. Thank you for your 4-star review! ### 4/5 — Super mais 3 petites choses à dire *2026-08-26* L’app est vraiment excellente, la plus propre et fonctionnelle que j’ai testé (et j’en ai testé pas mal !). 3 petits changements seraient toutefois les bienvenus : - sur l’écran d’accueil, l’app s’appelle « ProtonAuthentic… ». Un nom plus court qui ne serait pas tronqué serait évidemment mieux. - il est impossible de personnaliser les images illustrants les comptes. Exemple : un compte nommé « Amazon » aura bien le logo de l’entreprise mais un compte nommé « Amazon Julien » et un 2ème « Amazon Aurélie » auront droit à l’initiale du titre seulement. - pas mal de sites ne sont pas reconnus et n’ont donc pas droit à leur logo (Adobe, Airtm, ChatGPT, DeepL, etc…). Pourquoi ne pas laisser l’utilisateur importer ses propres images ? **Developer response:** Thank you for your positive review and feedback! We've passed it along to the team, so it can be taken into consideration going forward. ### 5/5 — Solid *2026-08-22* My go-to 2FA. Syncs to my other devices. ### 5/5 — MacOS Experience *2026-08-22, version 1.4.3* Works very well on MacOS Desktop, Best 2FA Authenticator ever🥰 ### 3/5 — Ganz OK, aber … *2026-08-13* Ansich eine Super App, aber ein Feature fehlt, dass ich nicht nachvollziehen kann. Ich nutze einen Passwortmanager. Dieser wird mit Biometrie entsperrt. Um die sicherheit zu erhöhen habe ich für einige Dienste 2FA, ebenfalls als Handy-App. Diesen möchte ich natürlich auf eine andere weise entsperren als meinen Passwortmanager. Bei Proton geht aber nur Biometrie oder eben nichts. Keine PIN kein Passwort. Dass kann doch nicht das Problem sein eine Passwortabfrage zu Implementieren. Ohne, ist diese App nur für Leute ohne Passwortmanager auf dem Handy oder Leite die den Passwortmanager mit was anderem entsperren als Biometrie. Schade eigentlich, sobald eine Umfangreichere App-Sperre integriert wird wechsle ich direkt! **Developer response:** Thank you for the feedback. We've added your +1 to the existing feature requests so that our team can prioritize them accordingly.

I don’t want to use biometrics on my devices. Ever! Nowhere was this behaviour discussed before I started using the app. I did not expect for it to be a case of use biometrics or be locked to your passcode. Disappointing. I do not appreciate the security risk Proton Authenticator has put me under. Passcodes can be overseen or otherwise stolen when used frequently from the plethora of security cameras and the ethics of those behind those cameras. Add the ability to create a custom pin/password so that my codes are more secure, please. The other missing customisation that I find with Proton Authenticator is that there is no way to customise the icons for the tokens/accounts. Any change to the title changes the icon into a generic letter that doesn’t stand out. If you have multiple accounts from the same company it becomes impossible to tell them apart. If you could add your own icon you could then group the accounts by client or in a way that makes sense. Right now it is very difficult to do that. To the actual authenticator. It does what you would expect. It is nice that you can see the code coming up next so you can start to type that in if there isn’t much time left on the current code. But that is something I think should be standard. I want to see you do better. **Developer response:** Thank you for the review. We've passed on your feedback to the team for future consideration.

You must log into your account. I use this program. Well you can’t do both at the same time. I do not recommend ### 1/5 — LOST EVERYTHING *2026-09-17, version 1.4.4* Opened app one day to randomly have no codes inside, thank god I had backups in other authenticator apps. Be careful… ### 1/5 — always server error *2026-09-03, version 1.4.4* not good, uninstalled. ### 1/5 — Broken liability *2026-08-08* The app only works on set up, after this of you need to sign in the codes do not work. Tried multiple times. This app will cause you to be locked out of your account. Like many proton offerings- poor implementation. Also tried the enhanced security- longer codes. These do not work ever! What a broken system **Developer response:** That doesn't sound right. Could you share more details about the issue? Are you receiving any error messages? Which web service(s) are you receiving incorrect 2FA codes for? Are the date and time on your device correct? Contact us using the "Feedback" option in the app settings so we can investigate further. ### 1/5 — Great app when it works *2026-07-30* I open the app and try to get my codes but its just stuck on the splash screen after face ID step. Looks like i will need to switch but not sure how as i cant get in the app💀 Figured it out its because im screen sharing (i am a mobile developer and always cast to my laptop) **Developer response:** That doesn't sound right. Could you share the specific steps you're taking that lead to this issue? How exactly are you mirroring your iPhone's screen (e.g. using QuickTime Player, or iPhone Mirroring)? Contact us through the contact form on our website with more details so we can have a better understanding of the behavior and help you further. ### 1/5 — Stopped working *2026-07-23, version 1.4.3* Stopped working with newest updates everything is crashing ### 1/5 — no code is working *2026-06-10, version 1.4.1* after the last update none of the codes work anymore ### 1/5 — Can't backup codes to Proton Drive *2026-04-30, version 1.4.1* 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. ### 1/5 — What have you done!!! *2026-04-22* 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. **Developer response:** Due to reliability issues with Apple's iCloud keychain implementation, we've switched to a new backup solution that works with any drive app, including Proton Drive, Dropbox, iCloud Drive and more. If you're having any trouble backing up your codes, please reach out to us using the "Report an issue" option in the app menu so we can help you further. ## Most praised reviews (10 highest-rated) ### 5/5 — Proton never disappoints *2026-10-17* Yet another example of how to do it right. Proton excels at securing our online experience. Zero complaints. ### 5/5 — Near perfect *2026-10-14* Fast, simple, not tied to a server. The best I’ve used. ### 5/5 — Excellent *2026-10-11, version 1.4.4* Does what it says on the tin ### 5/5 — Practical *2026-10-09* I’ve been using Proton’s other apps for the past few years and have no complaints. ### 5/5 — Mein Favorit *2026-10-08* Ich liebe die Ästhetik des Authenticators. Ansonsten ist es halt ein Authenticator und macht das was er soll. Was ich mir wünschen würde und was leider kein mir bekannter Authenticator bietet, sind Kategorien. Wieso kann man seine Codes nicht gliedern in z.B. Social Media, Shopping, Privat usw. Weder Authy, Google, Microsoft oder Proton haben dieses Feature. ### 5/5 — Perfeito *2026-09-28* Totalmente integrado entre os dispositivos ### 5/5 — Excellent *2026-09-15* Complète parfaitement toutes les applications de Proton. ### 5/5 — Best authenticator app *2026-09-11* 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. ### 5/5 — Excelente *2026-09-07* Super prático ### 5/5 — 五星好评 *2026-09-04* 可以显示下一组数字，很棒的设计 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
