Authenticator Pro user reviews :

Kudos to devs! Just one word to describe Excellent! Used 20s of different different auth apps, but everyone have one or more flaws, some were expensive paid, some have UI issues, some have customisation issuenand some have security. This one is perfect one. Perfect UI with useful customisation. Highly secure, backup is encrypted with your own seperate passcode (other than app passcode) and not mandatory to upload to cloud, take backup on secure pendrive and good to go. Impressive!

I love this app. Firstly because it supports wear os and Google ended support for their own app (which I still cannot believe). However, my only request is that when you are viewing the code on a watch you can’t see which site/app/company it applies to. It’s this a security feature? Because I find it more frustrating than your think, more often than your think. Along with the user name I would love it too repeat the app name!

very nice and polished, but as of the latest I seem to have an issue where it needs bio to unlock, takes it, then like… closes? I’m not sure if it’s in ram. I don’t think it should do that. LG G8X ThinQ on Android 10. Stock. edit: I’ll try and capture a logcat, if that’s any good.

  • Indeed, this has already been pointed out by a few users on GitHub. However, I’m unable to reproduce and find the cause of the issue due to a lack of information.

The perfect authenticator to start with! Nice looking and well organized interface. Stable work. BRAVO for listening to user request (to hide codes from screen and show only the necessary after having tapped on).

This is a great app, but my Wear OS device won’t display anything (TicWatch Pro 3 GPS). I tried everything but it doesnt work. I’m using the F-Droid version, I don’t know if that’s the cause tbh (don’t think so). Aside from that this app is destroying its alternatives. Great work! Edit: Thanks to the dev for telling me I need a github release wearOS apk for what, just sideloaded it and it works like a charm!!! By far the best on the market.

  • The F-Droid and Google Play versions cannot be used together, they have different signatures so they can’t be paired. Either download both versions from Google Play or sideload a Wear OS apk from the GitHub releases and it will work.
