Brilliant app - does just what it says on the tin

Had been required to use another app previously as a website required some form of 2fa but now it's more common I decided to research a bit to find an app that works on all platforms not just smartphones.

Picked this one as ticked all the boxes and open source and not some other mega corporation.

Totally happy and use it all the time. Simple to import from my previous app so now all on one site together.

Great app, one privacy issue

Went into the about section of in app settings so I could get the link to write a positive review, and saw the "send anonymous crash reports" setting was hidden here. It's very unusual for the "about" section of an app to have any actual settings, this feels intentional so the setting is missed and left on by default. Whilst the data policy for the app is otherwise good, in comparison to other 2FA apps, this is disappointing and if unintentional would recommend the developer move the setting somewhere more transparent. Will update my review if this happens!

Developer Response ,

Hi! Thank you for the feedback. The anonymous crash reports in our app are opt-in and are disabled by default, so it is in an unusual place so that people who don't want to share anything wouldn't have to think about it and those who want to help us with the analytics will find it.

Forced upon me

Authenticator app was forced upon me in order to continue using an essential website. Read many many reviews, some claiming to be free weren't, some seemed difficult to install/use. Eventually tried this one, and despite some troubles setting up, i got it up and running and no problems so far, fingers crossed.
I would recommend highly, but will amend review if troubles occur!!!

Developer Response ,

Happy to have you with us! Thanks for the recommendation and we'll try to ensure that you'll never have to amend it 😉😁
