## What is OTP Auth?

OTP Auth adds support for two-factor authentication to your iPhone and iPad. It can be used with Dropbox, Facebook, GitHub, Google Mail and many more. Make your accounts safe again!

Features:
- Ads free
- Encrypted iCloud Sync
- Siri Support
- Apple Watch support
- Notification Center widget
- Safari extension for pasting passwords into websites
- Secure application using Face ID/Touch ID (or password)
- Create encrypted backups of all accounts
- Import/Export encrypted accounts using AirDrop, iCloud, Dropbox, Mail, ...
- Works offline

All data stored by OTP Auth is stored using strong AES-256 encryption. This applies for all data. In particular, for both locally stored data as well as data stored in the iCloud Drive (when iCloud Sync is enabled). The password for those files never leaves your device such that noone but you can read your data.

OTP Auth does not collect information about you or send them anywhere. You won't be asked to allow access to your contacts or your location. And most important: OTP Auth does not connect to the internet and will not send your accounts to someone else! (Unless you enable iCloud sync where an AES-256 encrypted copy of your accounts is stored in your iCloud Drive. The password for that copy will never leave your phone.)

### 5/5 — This is the only otp auth for ios

*2026-05-01, version 2.18.0*

Simple, has every feature you would need.  Easy to use, can backup.  Its perfect.  This is the one to use, not some other limiting application from the usual suspects.

### 4/5 — Wonderful app, but possibly abandoned?

*2026-01-06, version 2.18.0*

This has been a fantastic app for many years. However, with the lack of updates, I am reluctant to use it. Is this app abandoned? I truly hope not, but understand if so. Thanks either way for making a great app!

### 1/5 — No App Support

*2025-12-01, version 2.18.0*

No response to multiple requests to support re password reset for the app. If you use this app you’re on your own.

### 1/5 — Stay Away

*2025-10-19, version 2.18.0*

Watch complications are broken and the Mac app can’t pull your cloud sync effectively making it broken. If you’re only going to use this on your iPhone, you’ll be ok but you’re much better off finding another app. This dev is MIA

### 1/5 — Passwords doesn’t work even though I put correct passwords.

*2025-10-19, version 2.18.0*

Good job, now I couldn’t unlock it even after I change the passwords again and again AND again. Please fix and know better.

### 3/5 — Worse since iOS 18

*2025-09-26, version 2.18.0*

Been using this for years. Whilst I'd appreciate a bit of maintenance to shave off some rough edges, this is probably still the best OTP/2FA app. Example: since iOS 18 copying codes from the widget doesn't work reliably.

### 3/5 — Decent

*2025-08-19, version 2.18.0*

This app is only free for iPhone and iPad; Mac costs money. Has a limited amount of favicons available without paying.

Other than those two big caveats, this app is great. But it’s 2025, and all functionality should be free. See Apple’s Passwords app, or Proton Authenticator.

### 5/5 — Great app

*2025-08-09, version 2.18.0*

Been using this for years. Whilst I'd appreciate a bit of maintenance to shave off some rough edges, this is still the best OTP/2FA app.

### 5/5 — 1 Top Rated Best Authenticator App!!

*2025-07-13, version 2.18.0*

I have had no issues with this authenticator 💯👍!!!
The app seems very secure with the 2FA features it includes and also seems to not collect any data when downloaded so it has built in privacy when I download it.
It's design seems great for what is free on iPhone and Mac app you get what you pay for to have it like the same iPhone concept, I been using this as my preffered authenticator instead of Google or Microsoft authenticators and others etc.  I enjoy using this app and have been for about 3 years or so.  A legit actual wonderful app on the app store!!!

### 1/5 — Lure you in with a free mobile app

*2025-04-27, version 2.18.0*

As per the title they lure you in with a free mobile app but the desktop app is £5.99. I have used the "Show Secret" function to export my accounts to the new Apple Passwords app which is free on mobile and desktop, with the added benefit it auto fills the 2FA on most sites.
