GREAT 2FA Solution

This Sentinel Authenticator 2FA app is GREAT.

I didn’t know what all it was capable of until I ran into a couple of difficult situations yesterday and put it through its paces.

This one inexpensive Pro/Premium purchase allows everything you need, including using it on your Apple Watch, which work seamlessly at activating codes.

And this app can set up codes manually and also allows importing of QR Code screenshots.

Surprisingly, it works on very old versions of the Mac OS.

Customer support is quite responsive in time and comprehensiveness, even on my OS 11.7.

An example was when my iPhone version asked me to upgrade to Pro. I already had Pro on my Mac. So I contacted support. They responded quickly and told me to click the upgrade link on the iPhone app. That resulted in the app saying I was already upgraded and the request to upgrade went away.

When recommending it to friends, tell them not to be confused with other apps named “Authenticator…”. Make sure it is created by Sentinel and/or Tommaso Carpi.

THE Authenticator App worth paying for!

I've used Google's free Authenticator App for years to store my 2FA tokens. Over the years I've had to change phones a couple of times and in doing so I've experienced duplicate token entries appearing for no reason and thus I've always lived in fear of 2FA tokens corrupting or deleting entirely – being locked out of any vital accounts I need to operate my business and finances would be an utter nightmare and the amount of time and hassle it would cost me makes it completely worthwhile paying/investing to remove the risk entirely:

Sentinel runs on iOS and macOS and sync's my 2FA tokens across multiple devices and has backups too (all secured with apple iCloud and keychain). The one-off 'Fusion Lifetime' in-app purchase is a no-brainer given how effective it is and the QR code import feature makes it ridiculously easy to move everything over from Google in an instant.

The developer is extremely friendly and responsive to questions and updates too! 5 Stars – 100% Recommend.

Really Good 2FA Service

This app provides exactly the kind of 2FA I want. Much better, in my opinion, than having a code sent to one’s phone via TXT. It’s easy to add the service to compatible Web sites and apps and has served me well for a long time. I use it on both desktop and mobile devices. The app is updated regularly and in the years I’ve been using it, has never had a problem. Thanks, Sentinel.

Best 2FA App hands down!

Fantastic UX, excellent functionality, dependable, secure and extremely responsive developer makes this a clear winner amongst a sea of 2FA apps. I’ve tried them all, nothing compares! Support a great indie developer!

Fantastic

Easy to use and to set up. Finally I have a simple too that does exactly what I need, without many unnecessary features. Direct to the point. Fantastic.

Authenticator is safe and so easy to use

Excellent app that works both on Mac and iOS devices. Easy to setup and integrates well into the Apple ecosystem.

Best 2FA & MFA App on the App Store

I have used pretty much every single authenticator on the App Store and each one is missing features that Authenticator has. I wish I would have found this app earlier. I would have had a great experience off the bat andI I would have saved money on bad 2FA/MFA apps.

I have used this forever. Great developer who listens to feedback!

This single app is the one which released me from using several different apps. I have been using this for years, and the developer is awesome.

Best 2FA app in the iPhone store

I Have used every 2FA app in the store. And they all are nothing like Authenticator!

Best 2FA Authenticator In Market

I’ve been using Sentinel Authenticator since Tommy first started building it. I tried all the others and came straight back to this. It’s simple, secure, and offers a seamless desktop/mobile experience. Pay attention Google and Microsoft. Hands down the best 2FA in n the market!

Best 2FA App on the Market!

I’ve used the app for years, across several versions, and across many devices. I use it on my laptops, phone, & tablet. It is BY FAR the single-most useful and versatile 2FA authenticator application on the market!! I use it every day and I love it. Feature package and ease of use is unparalleled. I cannot recommend it highly enough to anyone who needs a good, effective way to manage their OTP and 2FA accounts in an organised and easy to use app!

Best multiplatform 2FA app

I've been using it for a long time, it's very convenient, especially the sorting of services into folders.

Amazing apps. Saved so much time and super secured.

Amazing app. We stopped using Google Authenticator after seeing how awesome Sentinel is. Now, we rely on the security of this app for our daily uses.

My go to 2FA solution

I've switched from Authy, Google Authenticator, and Microsoft Authenticator to this app, and I absolutely love it! The interface is crisp, clean, and highly customizable, which makes it a joy to use.

One of my top priorities was seamless syncing across all my devices, and this app delivers perfectly with iCloud Keychain support.

Backups and folders function exactly as expected, making organization a breeze.

The custom icon selector and theme customization options are incredibly useful, adding a personal touch to the app.

I also had a great experience with the developer. I reported a few bugs with the iPhone widgets, and they were promptly fixed.

Overall, this app has exceeded my expectations in every way!
