Fantastic 2FA app

No account sign up required, lightweight, functional, good design, and iCloud sync so your tokens are securely backed up. There’s not much more to say. The app has frequent updates for new features/bug fixes. For example, I experienced the iPad Face ID bug, it was promptly fixed in a couple weeks. One suggestion, include an option (or make it the default option) to require Face ID authentication every time you open the app when it’s enabled. Right now, if you authenticate through Face ID, it allows anyone to open the app for an undisclosed amount of time. My current workaround is to force close the app after I copy my token. Keep up the good work.

Thank you for the feedback and the review! I'll forward what you said about Face ID to the dev team and we'll look into it. 😊

Update request. Read the reviews and let us know how things are going.

The reviews were perfect. Pointing out issues a new client will have and then addressing the issue turns this into a help feature. People need full service. The world that shunned technology is running this way. Let this be a lighthouse app. One that offers assistance to all the crazy people that don’t know that their adhd is preyed upon by ads. Showing the progress of the people and the issues they were having. Showing us the value of a place where sharp people are drawn to shore safely by shedding light on impending danger. I’m a flesh and blood, living, breathing human being. That means I’m weird, confused, and making progress because I made it here. For some people, this is progress. I am some people. I went ahead and shared the rough draft. However, this is my review of the comments since I haven’t decided on an app yep. Thanks in advance;) Give us an update of what can we look forward to in the wake of emerging technologies. Where can we get in front of the wave? Web Surfing in 2022.

Has almost everything I want in an 2FA app

This app has a nice UI, is intuitive and easy to use, and the file backup is a nice addition that I’ve only ever seen on computer apps or browser extensions. The biggest issue I have with it is that when I turn on Face ID, it doesn’t quite ask for the Face ID every time I open the app. If I want a protected app that asks for Face ID at all, it defeats the purpose for me if it doesn’t ask for my face even AFTER I TURN THE PHONE OFF AND TURN IT BACK ON. This is one of the hugest reasons that I deleted the app and opted for another authenticator app. The other reason is that I wish there was an option to omit an icon/badge/label altogether. This is picky, I know, but I either want every entry to have a logo icon or I want none of them to. And this app doesn’t have the ability to get rid of the icons.

Developer Response ,

Hi, thanks for the review. I'll forward the idea about no icons to the team, and I'm sure we will have it in future updates. Now the FaceID. If you use it to unlock your phone, it authorizes our app to unlock because your phone knows that you still have it in your hand and doesn't need additional unlocking. When FaceID unlock actually happens on our app, it's so fast that most of the time, it's almost unnoticeable. So it's Ios that authorizes our app, and we can't change the Ios system and fight against it is not wise. Please reconsider coming back to us! 😊
