App is being constantly developed with new feature being added. Currently the support for Steam. Developer listens to the user ratings here. Keep up the good work!

Works well on my watch, and is one of the only options for wear os. Very easy to add codes on the phone, and the watch has access to all the same code generators. Along with a touchscreen interface, it utilizes the scroll wheel if your watch has it, a nice touch that some apps lack. My one gripe is that it doesn\'t work without a phone connection (watch can\'t be in airplane mode). On the other hand, I don\'t usually need access to a code for the few times I don\'t have my phone with me.

Fantastic Android and WearOS app. Beautiful, clean and simple. Offers local backup (unfortunately not to cloud, but that\'s on purpose to limit the permissions required). One feature I wish was available would be \'last used\' or \'favourite\' entry for the wearOS app My corporate account is used 90% of the time compared to all of the other ones and this would minimize scrolling and taps. With that feature - 10/10! FEB 21, 2021 EDIT: dev listened & default entry now available on WearOS. Amazing!

Love this authenticator... I really missed the wear os integration when it went missing from the Google Authenticator. Very glad I found this. I also appreciate that it\'s open source so anyone can do a security audit or submit patches. Thanks so much for this, keep up the great work!

Excellent Work! This app is nothing short of a miracle. It is one of the most well designed and thought out apps on the entire Play Store. What makes it even more awesome is that it is open-source and free. More importantly, I would suggest you to insert a \"Buy me a coffee\" button in the app. It won\'t hurt anyone as long as it\'s not compulsory. I was actually looking for it. ;) Edit: Amazing update! You\'ve just made this app complete and very competitive.

This is my favorite authenticator app by far. It has all the authentication protocols you need, automatic backup, huge built-in collection of icons, imoort compatibility with most authenticators (including Steam and Blizzard !!!) and much more. I still have a few small requests to make it absolutely perfect, but those can be made over at GitHub. The dev is very responsive and frequently updates the app. I whole heatedly recommend this app.

Great replacement for unmaintained Authenticator+. Cloud sync is not available but I understand the reasons explained on GitHub, and other apps can manage this synchronization if needed (FolderSync seems to do the job). More options than Authy (tags / category, auto lock delay, ...) Good for users with many 2FA accounts (may be a more compacted list view will be great :) ). All the websites I use have already the right icon ♥ (except 1&1 that should be updated after Ionos acquisition ;) ).

I love the idea of the app and I\'m sure it works. However, I have two step authorisation turned on. So my password is correct, but then it asks me to go to Facebook and obtain the generated code form there. But because I\'m on a new device and not logged in elsewhere, I can\'t login to my account.
Russ Mace 2020-12-15

It\'s nice.. You cannot select a different code to the one at the top of the list in the wearOS app and it\'s driving me nuts. I love it but it\'s not usable on the watch which is the only reason I moved to this app because Google are doing a rubbish job on the wear is app also.

I bought a WearOS smartwatch and thoughr \"Gee, it would be swell if I could get all these 2FA OTP codes on my watch seeing as it\'s easier to get to.\" Why Google took WearOS support away from their own app is probably the sad reflection of how they\'re treating the platform. Well, Authenticator Pro supports WearOS, so I can get codes right on my watch. It\'s free and actively supported (unlike the other auth app) and in true FOSS style, no ads. It generates codes. Works on my watch. Looks good.
