  • A good start - Please sort alphabetically

    This app is off to a good start and can import from nearly everywhere. The ordering of the services/codes seems random, and even when searching, it’s not alphabetical. It would be useful to make it sort alphabetically.
  • Great

    I have 48 2fa accounts. App lags a little on the main screen. Otherwise, fantastic.
  • Love anything Proton

    No import option for ID.me … Manually it will have to be.
  • Unable to Sync/Login on iPad

    On iPhone I had no issues getting setup. On iPad, when I try to enable sync, regardless of if I use Yubikey or OTP to authenticate, its loops back to login page and never logs in/enables sync. Hesitant to start relying on this for 2FA or to move my codes over when I can’t login on a device. Will update review when this is resolved.
  • Multi device sync doesn’t work

    I have an existing Proton account. I imported all of my MFA codes on my iPad and successfully enabled multi device sync. Trying to enable on subsequent iOS devices puts me in a login loop. It’s not multi device if one cannot enable on multiple devices.
  • Rushed roll out

    Can’t sync on iPad or Mac. iPad app is super glitchy. This will probably improve a lot but rn not usable across devices
  • Not there yet

    Works for me on iPadOS, MacOS, and Linux. For some reason will not login or synch on iOS. I will change my review when it finally works.
  • Shockingly Poor Quality

    I can’t recommend this app on anything but iPhone. Works fine there. You can’t log in to connect to your Proton account on other devices because the 2FA input is broken. On my iPad, the screen strobes for about 5 seconds before you get the Touch ID prompt. Shockingly poor quality from Proton, hopefully no one with epilepsy tries to use this on their iPad.
  • Awesome 2FA app on multiple platforms

    Would be great if: (1) Have a native MacOS app. (2) Can choose to hide item’s icon (e.g., Netflix logo)
