    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)

    On iOS the search often ends up stuck on the middle of my screen making only the top half scrollable!

    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.

    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!

  • Very nice app

    I love the look of this app. Its very modern layout is gorgeous and it’s pretty simple to use. Just scan your QR codes and you’re ready to go. You can even transfer codes from another authentication app. Great job Proton team!

  • Excellent to have this for Mac.

    This is really a game changer having this on your desktop. I hate having TOTPs inside password managers, so this is an excellent alternative that still allows me to easily access them on my Mac (which is most of my screen time).

  • doesn't appear to work with VoiceOver

    I downloaded this app and unfortunately it doesn't appear to work with VoiceOver easily, or at all for that matter it does initially when you get everything set up, but whenever you import your codes and everything, it just doesn't work with voiceover at all

  • Good Authenticator

    I’ve been using Authy for awhile so I was excited to see Proton released one which offers better privacy. Unfortunately I can import all my codes from Authy. Its a bummer having to do them all over one by one. The other improvement I would like to see is being able to organize them in the order I use them from most often to the least often. It’s new so hopefully Proton has more updates in the future. Would still recommend it. Keep it up Proton.
