What do you like best?
The Authenticator is as straigthforward as it can be. Install, register a new account for 2FA authentication either manually or scanning a QR code, and you're done. You can store as many as you like in your mobile device and it has a very nice feature of copying the generated token code just by tapping and holding over it.
What do you dislike?
Actually, nothing! There's nothing off with this handy tool! Maybe, just maybe, the capability of changing the format of the countdown timer (currently a decreasing pie chart) for other options, such as a gauge or an actual numeric display, but this would e a nice-to-have feature, not something that impairs the operation of the app.
Recommendations to others considering the product
Use it with total confidence. It's one of the most easy ways to implement 2FA authentication features in your access levels. It only requires a compatible mobile device, such as an Android-based mobile phone with camera, and the required configuration in the respective account that requires a two-way authentication method. Even if not required, if there's an option for 2FA, we encourage you to take advantage of that extra protection layer and leverage it with Google Authenticator. Also, remember that it's free, so there will be no extra cost of deployment in your premises.
What business problems are you solving with the product? What benefits have you realized?
Several of our accounts require, or have the option to, 2FA authentication for an extra layer of security at login. We just consolidated them using Authenticator in our employee's assigned mobile devices.
