Pros Easy to use and secure way to protect your account.
Cons Can be inconvenient if you lose your phone or if the app malfunctions.

Comments and Reviews from users:

Tony Arroyo: “Getting better. Now it has Google cloud backup, but it's debatable if you want to back it up there. If your Google account is compromised, you could lose all your accounts. There's still no security authentication on the app itself, so it's only as secure as the access to your phone is. Google desperately needs to provide a PIN code or biometric to access. Also needs the ability to transfer to other platforms.” – 3/5 in Play Store

Walter Prochorenko: “Very difficult to use. I installed it for 3 accounts but the 4th was just impossible. Don't know if its the fault of the client or that of Google, but getting a message that I was using unacceptable characters was frustrating since the characters came from a Google password. No one appears to be trying to work with the clients anymore. If one is exceptionally gifted in the huge variety of words, phrases and descriptions used by the tech specialist, then fine - but the rest of us are clueless” – 4/5 in Play Store

Comments and Reviews from users:

Heather Thyssen: “Pretty darned reliable, and remarkable in keeping things up to date ( compared to Google Password Manager). A missing feature: it doesn't restore all accounts from a backup; rather, it restores the main account and passwords. I've lost access to a Microsoft account, and if the backup would have restored all the accounts I had signed in on this application, I would have given it two more stars” – 3/5 in Play Store

Jen Beck: “Using Microsoft products, for me, is a pain. I always forget my password or they don't seem to match between computers or applications. This makes it super easy to approve a sign in and not go through my list of saved passwords to try to figure out what passythe app wants to use today. I don't have this issue with other compy, but for some reason I am a dark cloud when it comes to Microsoft.” – 5/5 in Play Store

Comments and Reviews from users:

A Google user: “This is for the 9th October update. I stopped receiving the notification sounds. Digging in, I found the app's default settings was to use a built-in notification sound. Looks like that sound is missing in this update. I picked one of the Android notification sounds and all is good now. Looks like this particular release might not have been tested thoroughly before release. Over all the app has been pretty good. No delays in getting the notifications, or in the "approve" message being sent back to the server. Edit: I am on Android 9 Pie Edit 2: I now have the new version, 3.32.2, build 323206. The notification reverted back to "App provided sound" and still no audio notification. It does vibrate. Edit 3: Issue in edit 2 turned out to be my phone. Restarted it and all is good now. Changing app rating to 4 Stars (There's always room for improvement! 😉 )” – 4/5 in Play Store

A Google user: “Very annoying app. The worst part is that the push notifications just don't work. I have to manually open the app to see the request and approve it. Then, a few minutes later, the push for the original request will finally show up in my notifications, by which point it's useless and I don't need it anymore. Also, I emailed the support email for the app store to mention my issue and all they said to me was that the email support was for paying DUO users. Why put that email for the free app?!” – 2/5 in Play Store

Cons May not be compatible with all websites and apps; Push notifications may be unreliable at times.

Comments and Reviews from users:

A Google user: “This is a welcome improvement over Google Authenticator, and appears to have advantages over LastPass authenticator, as it runs on both mobile devices and desktops. It needs, however, the ability to SORT accounts by user-defined CATEGORY, NAME and PRIORITY, as well as the option to HIDE infrequently used accounts. These options would decrease screen clutter, and make it MUCH easier to find most-used accounts w/o the scrolling which is presently required. If these features were added, I'd happily pay a reasonable one-time fee for it. I do like it already, but it's too close to being better for the developer to leave it where it is. EDIT: Turns out, you can ALREADY drag to re-order accounts in the Android app. The CS response to my request for that didn't seem to know this. But, AFAIK, still NOT in the Windows app.” – 4/5 in Play Store

A Google user: “Very confusing and unwieldy. All I wanted was to authenticate Discord to my physical phone, and instead of just doing that, this app wanted to authenticate itself to my phone (even though it was already installed. ??). The mere fact that it was on my phone should have been enough to do the authentication. Unwieldy because it wanted me to copy a large code from my text app into the app which requires switching between two open apps on my phone. Switching between the apps then blanked the input dialog, making it impossible to enter the code. I just gave up.” – 2/5 in Play Store

Cons May not be compatible with all devices, and can be annoying if you lose your phone.

Comments and Reviews from users:

A Google user: “I found this app to be the most frustrating app I've ever used, at first. It took several tries to accept a login attempt with no indication of why it failed. I finally realized months later that this app does not handle Google's data saver feature very well. The solution for me was to grant this app unrestricted background data in the data saver settings. After that change it works well. I still wouldn't recommend this app until it gives better feedback on when or why it is failing.” – 3/5 in Play Store

Michael Rooney (roonbaob): “This app sorta works, but it feels like a team made it who doesn't use it. The push notifications often fail to send with no retry or failure notification. Then I have to open the app anyway, at which point a failure notification pops up on the bottom *blocking* the button I came there to click! This often causes the app I'm using to time out and I have to start over. Asking other team members, this seems like a normal experience. But if you are reading this you probably don't have a choice :)” – 3/5 in Play Store

Comments and Reviews from users:

A Google user: “Thanks for the app that simplifies lots of tasks for me. I'd like to report a minor issue : about 2/3 of the times I use the login, the app stops (the app simply stops working without any message, and I'm brought back to my home screen) working when clicking "confirm" during authentication process. I then have to relaunch the app and start over. It never fails on second attempt.” – 3/5 in Play Store

Gustavo Bohlen: “Love the idea and concept, but implementation is not customer friendly, it's slow, cards take up to a minute to appear and sometimes it isn't able to authenticate and login into the website. It's already a hassle to take my phone up when logging in somewhere, you should make it snappy and quick, with the least amount of actions for me to do! Please improve, there's so much unexploited potential in this! Also, make it less Belgium specific if you plan to expand in Europe!” – 3/5 in Play Store

A Google user: “Even after setting the notification to silent or even completely off I still get the authentication prompt with a loud alert sound. Please fix this! Thanks! Also sometimes the finger print "layer" doesn't come to the top and the OWA screen doesn't have a "try again" like other apps do. I just have to wait for it to time out and then open the link again on the computer. I just switched from iPhone 7 to Samsung S10 5G and I didn't have these frustrating problems on the iPhone.” – 2/5 in Play Store

Dwayne Collingwood: “Issue 1: App re-opens after I back out of it, every time. Why? Issue 2: Could you please add an option to disable the "number-flip" graphics? Yes, it's cool but when you use this 100 times a day, waiting for the flip and having it pause / hesitate mid-flip every time you need a new number is so very annoying.

Blake: “Created an account without issues, and have been using it ever since - the majority of online services in Estonia support this app as a login method. Its very fast and convenient. After 2 years of using the app, it had never failed me, did not have any issues so far. Keep in mind that if you have Blokada or something similar, it will block app notifications, so you would need to whitelist the domain that Smart-ID uses.” – 5/5 in Play Store

David A Leija: “*Edit (again) : Thank you for adding the ability to back up to a local file. This 2FA keeps getting better! *Edit: New update is amazing. Being able to sync and back up through Google Drive is a great feature. Ive already used the function and it works seamlessly. This app officially blows any other authenticatior out of the water now.” – 5/5 in Play Store

Miguel Borromeo: “Easy enough to use. I don't necessarily need biometrics or a pin to access the codes though because I already have to do biometrics or type in pins for the app I'm signing into with 2FA and a password manager, and it's a little frustrating to switch between them. It would be nice to have the option to enable them when editing any of the settings. Unfortunately, it's an all or nothing affair. Edit: I mean disable them for getting the one time codes, but enabled to access the service keys.” – 4/5 in Play Store

A Google user: “Generally does the job, no issues with authentication so far. However I had login via fingerprint enabled, which seems to use the fingerprints already stored on the device for unlocking, then added more fingerprints for unlocking.

A Google user: “Its "OK." With exception to the backup feature, which is excellent, the rest of the app is minimally functional. Times are changing, long lists are not unusual. There needs to be a search field, and if there were also sorting and categorising features, the rating would be five stars. However the app has barely changed in all the years I've used it.” – 3/5 in Play Store

A Google user: “I appreciate the backup feature. However, the app would be much more useful if I could rearrange the entries. (I have tried long-pressing entries to no avail.) Apparently, the last entry added goes to the bottom so my list is quite random. I have to scroll through all my entries, find the correct one, and enter the code within the time allowed (30 seconds I think). At least, I can rename entries so I recognize what I want.” – 3/5 in Play Store

Changing picture for account is just buggy automatically changing picture from mine to something else when I do not change it (editing name) 3. Brands list too short 4. Please remove that useless star icons to leave more space for account names (usually email which can be pretty long), also that popup menu button is useless too, to open item menu you should use long tap and to copy value - short one.” – 3/5 in Play Store

Comments and Reviews from users:

A Google user: “Wonderful new 2FA app! I've been looking for one with password security and the ability to use the phone's fingerprint sensor to open . It seems logical that you would not want to allow 2FA codes to be obtained if the phone was not in your hands ... other apps I've tried do not provide this additional level of security. I have ONE quibble though ... the app does not automatically "Log Out" or lock itself. I have to do this manually. Please include this as a feature ... perhaps an auto time-out that can be set? Not having the app lock itself seems to defeat the purpose of having the lock in the first place! Other than that, kudos to the developers! And notwithstanding this shortcoming ... which I'm SURE you will address ... 5-stars to you! Don't make me come back and change it! :) :)” – 5/5 in Play Store

A Google user: “This app far exceeded my expectations! The security of this 2FA app surpasses any similar app, mainly because it has security options and the other apps don't. I very much like that I can hide all codes and only show what I need. I've only had one minor issue, and that is its cooperation with lastpass. Lastpass pops up to input the password, but I just want to use the fingerprint method. Upon closing the lastpass pop-up, it won't take my fingerprint. I'm certain that I can stop lastpass from popping up for this specific app, but I don't understand why this app stops accepting fingerprints after it does.” – 5/5 in Play Store

Pros Authenticator Pro is open source, has a clean interface, and supports a variety of 2FA methods.
Cons Authenticator Pro does not have as many features as some other 2FA apps, and it can be difficult to recover your codes if you lose your phone.

Comments and Reviews from users:

Stephen Schrauger: “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.” – 4/5 in Play Store

Maciej Sawicki: “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!” – 5/5 in Play Store
