### 3/5 — Nice app but…

*2026-08-13, version 5.4.4*

The prompt to review when I open it to get a code is an infuriating thing.

Also, having to join a discord server just to suggest that maybe there should be an icon for a particular service or website?! Bah!

### 5/5 — Nice and flexible

*2026-07-15, version 5.4.4*

Simple, flexible, great

### 2/5 — Good concept but flawed

*2026-07-09, version 5.4.4*

The push messages are really flaky. I receive the push message, but the app doesn’t always process it properly so it very rarely actually sends a TOTP back to the mac, so I have to manually type it like 80% of the time

### 5/5 — Best OTP option for iOS, open source or otherwise

*2026-07-08, version 5.4.4*

Other options like FreeOTP don't let me view or export the secret, but 2FAS does.
I only wish the app was more discoverable: It doesn't show up when I search for OTP without scrolling wayyy down, and other OTP authenticators are in the Utilities category, while 2FAS is in Productivity.
Very glad I found it, though!

### 5/5 — 2FA alternative that works

*2026-07-08, version 5.4.4*

If you’re looking for a 2FA alternative to Google and Microsoft that works, this is it!

### 5/5 — Simple

*2026-07-02, version 5.4.4*

I appreciate a FOSS authenticator being here, so I can secure my various online accounts more easily.
No ads, no corpo cruff, just an app you can rely on.

### 4/5 — Ravens

*2026-06-27, version 5.4.4*

Raven

### 3/5 — Does this support SHA256 and SHA512 hash algorithm?

*2026-06-25, version 5.4.4*

The other 2FA apps don't support it.

### 5/5 — Amazing, Amazing, Just, Wow!

*2026-06-19, version 5.4.4*

I use this app for an authenticator for 3 apps, Roblox, Discord, and Google. This app is really good for that, it even has the app protection which I can set a pin in order to get in. 5 Stars!

### 4/5 — a fine authenticator app

*2026-06-15, version 5.4.4*

ui is clean, does its job. if i had a gripe about this app it would be how it takes a while for it to start showing real authenticator codes after the ui load, like a whole second needed, which is not horrifically slow, but absolutely annoying

### 3/5 — Good Not Great

*2026-06-12, version 5.4.4*

The web extension does not work with Gmail. The codes are wrong every time. Very time consuming to have to manually type in codes. Please fix this.

### 5/5 — Top Notch

*2026-06-10, version 5.4.4*

Private. Secure. Functional. The best and one of the few apps I recommend to friends, family and anyone that asks for my opinion.

### 5/5 — Gets the job done

*2026-06-09, version 5.4.4*

easy & minimalist, open it up, get the code, get out. good stuff.

### 4/5 — Works as expected

*2026-06-09, version 5.4.4*

Works as expected.  

Can you add an option to have the widget on lock screen always show the number? (I know it’s not “secure” but saves me from logging in). 

Can you create it for Amazfit watches?  Thanks

### 3/5 — Great but unfortunate that they took so long to implement e2ee in iCloud.

*2026-06-05, version 5.4.4*

It’s been several years since 2FAS was rejected by PrivacyGuides due to a botched implementation of end-to-end-encryption in iCloud backups. The fact that this was botched in the first place is troubling enough, but even worse is that it took 3 years to improve it. How many people were left at risk using the backup while 2FAS took their time to fix it? 

I like the app, but I am not confident the 2FAS team know what they’re doing in terms of privacy. Check threads on PrivacyGuides for deep details. It’s quite disappointing. Anyway, 2FAS has claimed to have released a fix in 2026, but that to my knowledge hasn’t been audited externally, so I still haven’t enabled iCloud backups.

### 5/5 — This is the best  1 fraud protection program out there

*2026-06-05, version 5.4.4*

Approved by Leek the greatest syner security man ever’

### 1/5 — Compromised

*2026-07-29, version 5.4.4*

Everything about this security is garbage , it ruined my entire life because everything I own got hacked. New bank accounts, SECRET BROWSERS , and even my bank accounts.

### 1/5 — No success

*2026-07-22, version 5.4.4*

Tesla app need 2FAS to generate a 6-digit code but 2FAS not cooperating

### 1/5 — Accesses the camera

*2026-07-16, version 5.4.4*

This app was accessing my camera at random times. Make sure you revoke camera access. Shady company.

### 1/5 — Poor

*2026-06-07, version 5.4.4*

Basically 30 seconds to jump from app to app  to input a 6 digit code is ridiculously 
short

### 1/5 — Гугл профиль,сделайте пожалуйста синхронизацию с гугл акаунтом для айфона

*2026-05-27*

### 1/5 — Codes don’t work

*2026-05-05, version 5.4.4*

Codes don’t work no one to talk to about this 5 thumbs down

### 1/5 — “update”

*2026-04-24, version 5.4.3*

It has been “updating” for MONTHS. I can not access my 2FA, I can’t even sign in with my accounts that have 2FA. Most secure thing can’t even fix.

### 1/5 — Easy to use

*2026-04-21, version 5.4.3*

I hate this app. Never works for me.

### 1/5 — Don’t use

*2026-04-16, version 5.4.3*

Many users, including myself, lost all 2fa after updating app. Dev team didn’t help us. Locked out of many accounts. Don’t trust them

### 1/5 — Auth tokens disappeared

*2026-03-28, version 5.4.2*

I have used this app for a couple of years and it has worked well but did an update a few days ago and ALL of my tokens disappeared! It was like they never existed. Really disappointing. Unfortunately because of this I can’t give this app more than one star as the core function of the app failed.

## Most praised reviews (10 highest-rated)

### 5/5 — Works like. Charm!

*2026-08-24, version 5.4.4*

I’ve never had an issue, work great.

### 5/5 — Just remember to back up to iCloud!!!

*2026-08-21, version 5.4.4*

This is your only path to recovery… so turn it on


Otherwise this rocks!

### 5/5 — Great but a question.

*2026-08-15, version 5.4.4*

So far I have no issues, works as intended. I just had a question that is it possible for this app to loose all my auths or for the app to shut down, is this a possibility or do I not have to worry about loosing anything?

### 5/5 — 2FA Authenticator (2FAS)

*2026-08-14, version 5.4.4*

I love this app it transfer all my data from google Authenticator at easy

### 5/5 — good

*2026-08-09, version 5.4.4*

nice

### 5/5 — Everywhere You Want It

*2026-08-02, version 5.4.4*

As an everyday user who has to rely on these second layer authentication apps, I liked this one the most because of its simplicity and organization. It not only has a way to categorize and color code your entries, but also has an easy way to back up, restore, and share whenever needed.

### 5/5 — Works Great

*2026-08-01, version 5.4.4*

It works. It’s fast. No problems.

### 5/5 — Basically Perfect

*2026-07-30, version 5.4.4*

Great looking app. Well designed, fast, and functional. Seemingly quite good data handling policy. Oh and it’s free. What’s not to love?

### 5/5 — Auth tokens disappeared

*2026-07-27, version 5.4.4*

UPDATE: A few months back all of my tokens disappeared after an update. I did receive a response from the developer asking to check the trash and sure enough the tokens were indeed there, which made me very happy and I reconsidered my earlier decision to stop using the app. I also updated the star rating to reflect this. Big thank you to the developer for going the extra mile!

### 5/5 — Brilliant

*2026-07-15, version 5.4.4*

Great app for local storage of OTP
