Simple and Secure
Got this authentication app after I almost got hacked using google authenticator and decided to switch to a new Authentication app. When I got this app I was easily able to sync through my phone and iPad using the iCloud feature. It also has a feature to ask for a passcode first when logging in which means if I lose my phone or iPad, I won’t be hacked. 5/5 stars.
do not download
i accidentally uninstalled the app while clearing up storage then once i re-downloaded the app all my codes were not sending and i have been logged out of every single on my my personal very important accounts i have asked support no help google support on there site no help don’t make my mistake by downloading this app
Great choice for MFA
Open source, convenient Backup, easy to import and export, free and add-less funded by donations, What more could you want?
Great solution
Recently moved from Authy, which I thought was good but 2FAS is even better. Highly recommend.

Stop asking for a review as I am trying to enter the number
Does not work
I have been locked out of accessing my sites/portals
When the 2FA is manually put in or pasted it is not accepted
I’m using the same device that was used previously with no problems before. And now I have no way of accessing anything that has a 2FA
DO NOT USE THEY WILL STEAL YOUR MONEY
I just downloaded this app and moments later they stole everything from my trade ogre account. I am not sure if they got hacked or they have done it either way do not use them
Simple but Perfect
I've been using the 2FA Authenticator on my iOS device and it's made my digital life so much easier and secure. What makes it stand out is how it syncs with iCloud, removing the need to remember any extra usernames or passwords, as it's all securely stored within the iOS system. This simplicity is matched with great security, making me feel at ease. It's a breath of fresh air in the realm of authentication apps, integrating flawlessly with my device and streamlining the two-factor authentication process. For anyone using iOS, this is the 2FA app to get!
Great

I can’t tell you how many times I have lost my codes because I had to reset my phone
