Easy to work. Clean interface. Definitely worth donating to their cause.

PIN changed

NevvyRen on

United States

For unknown reasons, my PIN no longer works. Now I’m locked out of a dozen accounts until this miserable app decides to accept the only PIN that I’ve ever used for it. What a joke.

Updated Review - Icon not shown correctly

FeelingOutshined on

United States

I’m completely renewing my review because I discovered what the issue was. I originally thought the token was removed right after adding it & I had lost access to my game account (which I did until I caught what happened). The Square Enix logo icon (the game co) defaults to Square logo icon (the point of sale system co) in 2FAS, and changes the name to drop the “Enix”. So it shows just simply Square, with Square’s logo. I didn’t notice because I also use Square. It would be fantastic if it were possible to add custom icons for tokens, but you’d think 2FAS would already have the icon for such a huge gaming company (and not change the name in the process). This was absolutely panic-inducing to go through.

How do you get it off your phone

Your 2FA App Should Not Collect Data

Trshpl7 on

United States

And, this one collects the least. Easy choice. App is well written, great options for exporting, manual manipulation, security.

Good app but zero support

okgreygfyfrystshg on

United States

The app itself is fine and has most of the functionality I want. But if you ever have an issue there is no way to get help. The only form of support is a Discord, where they copy paste the same responses at you. If your question doesn’t easily fit one of the pre written responses you just get ignored. New icon submissions take months to add, if they ever get implemented. There’s also been a data loss bug with imports that has been open for months with zero response, which is very worrying. Edit: Despite the contact offer in the developer response, I still have not been able to reach anyone. All the issues above are still true.

Efficient, Clean, Useful

gnomechimpsky on

United States

This is a great two-factor authentication app. It’s simple to use, and has an efficient layout and set-up process.
