2FA review

I need this app to get access to my classes but the fact that there is a 30 second timer to put a six digit code is kind of dumb

Great

Does exactly what I need it to including backup to cloud which makes it available on all my devices. Props to the author.

The best 2FA application period!

I absolutely love 2FA authenticator because of the very high level of privacy and security compared to other 2FA apps. 2FAS does not collect user data and the privacy policy is transparent and understandable. 2FAS automatically backs up authentication tokens within iCloud but you can also export the 2FAS backup with a password so it can be stored on other devices and such. 2FAS is the absolute best and there’s no debate on that.

Reduced the font size to unreadable

I’ve used this app for a few years, everything was fine until they ‘modernized’ it. Meaning they reduced the font size to barely readable and nothing else changed.

Best Authenticator for IOS & Android

I wrote a review already for Android but the developer deserves all the positive reviews they can get. Compared to this app, Google Authenticator seems to have been written by a child.

Not to mention that Google randomly deleted all my keys - on device and cloud. My advice to anyone who is still using Google Authenticator, switch quickly before the same happens to you.

To the dev team - thank you for an outstanding product. You can see how much effort has gone into it. It’s installed on all my devices now.

Awesome

Doesn’t hack

Big problem without iOS 18.6 or later

App apparently won’t update properly if you are using an older version of iOS.

Apple Watch hard to use

The Apple Watch app needs to be improved. I have keychain sync turned off so the Apple Watch won’t work. I wished I knew before I downloaded it in order to avoid this app.

I also don’t like the idea of iCloud sync being enabled by default.

Nice solution for iPhone and watch

I’ve been using this app for a while now and really appreciate the sync capabilities between my iPhone and Apple Watch. The latest update created additional black space between the tokens, effectively reducing the text size, making it more difficult to see and I don’t see a way to adjust it font size. Otherwise a great app!

Like it a lot!

just switched to this from authy. liking it a lot, but the apple watch minimum version being 26.2 prevents me from installing it on my SE. :<

Old Appearance Was Better

Now it looks like every other one I’ve used.

The best and easiest to use

I cannot say enough good things about this app. It makes it simple to secure your accounts. Backup and recover are easy. Highly recommend.

Had this app for almost 10 years and I love it!!

I’ve never had one issue with this app in all the years I’ve had it! I changed phones twice and it kept all my information. 10/10 my fav authenticator app!!

Nice and functional

Very well designed and practical. I love the widget function that quickly enables me to access daily to a website. Very easy to import/export codes from a previous code generator app. Hands down 5 stars!

My review

My phone has a virus and is being monitored so therefore my phone won’t let me use 2FA

Good 2FA App

I’ve been using 2FAS for about 3 years, never had any problems with it. Very clean , there are no ads which I really appreciate. The backup function is really nice , I have it many different places just in case. I would advise anyone who is going to use this app to take some time to understand how the file backups work and maybe do a dry run. great app

Need to upgrade the app

If you lose your sign in code theirs no way to get a new one that’s not good. It automatically locks you out of everything you use 2FA for. Make the app so you can get a new code if you lose it. Without being able to get a new password once loss makes the app worthless and janky

Loved it since early 2025

I got this app as part of my push to de-Google and have had no problems. It Just Works. It's great to have 2FA that isn't part of big tech, thank you developers!

So muss das

Absolut empfehlenswert! Tut was es soll und ist dabei übersichtlich und gut strukturiert.
