## What is FreeOTP Authenticator?

FreeOTP adds a second layer of security for your online accounts. This works by generating one-time passwords on your mobile devices which can be used in conjunction with your normal password to make your login nearly impossible to hack. These passwords can be generated even when your phone is in airplane mode.

FreeOTP works with many of the great online services you already use, including Google, Facebook, Evernote, GitHub and many more! FreeOTP also may work for your private corporate security if they implement the standardized TOTP or HOTP protocols.  This includes great enterprise solutions like FreeIPA.

FreeOTP is open source and free software! Licensed under the Apache 2.0 license, you can obtain the source code for FreeOTP at https://fedorahosted.org/freeotp for review or modification. Contributions are welcome!

### 5/5 — Genau der richtige Authenticator

*2026-05-15*

Hervorragende Alternative zum Google- bzw. Microsoft Authenticator. Macht genau das was er soll.

### 5/5 — Quero desvincular meu cpf deste aplicativo

*2026-05-13*

Não consigo acessar

### 1/5 — Won't load new QRs

*2026-02-16, version 2.3.6*

I was happy with this app. But the last two times I tried to add a new website. It will not load the QR code. I've checked for updates in the App Store and there's nothing there.  Too bad it was working fine before this.

### 5/5 — Chinese

*2026-01-31, version 2.3.6*

加个中文呗 这也不难 这个工作量不大 这软件没啥别的功能 汉化不多 主要是简洁确实简洁 安卓版都是汉化 有中文 iOS顺道整下

### 1/5 — Crashes on iOS 12

*2025-12-09*

Version 2.3.5 was fine, it was recently updated to 2.3.6 and that one crashes on iOS 12, so impossible to access services with TOTP stored in this app.

### 1/5 — Parou de funcionar

*2025-11-28*

Troquei de aparelho e não roda mais no IOS da Apple. Deve ser algum bug

### 2/5 — Bad

*2025-09-29, version 2.3.5*

Unable to delete

### 1/5 — not recommended

*2025-09-28, version 2.3.5*

The app only allows you to add OTPs, but you won't allow you to transfer them to another app or device.

### 5/5 — Kostenlos und trotzdem  sehr gut

*2025-08-31*

Tut was man von so einer App erwartet. Klare Empfehlung

### 1/5 — Does not work at all

*2025-08-18*

Worked fine since years bit  today I cannot open ANY of my keys they are all locked. By the way there is no way to EXPORT a key

## Frequently asked questions about FreeOTP Authenticator

### What does FreeOTP Authenticator do?

FreeOTP Authenticator generates one-time passwords (OTPs) that add a second layer of security to your online accounts. These temporary codes are used in conjunction with your regular password to make logging in much more secure and difficult to hack.

### How does FreeOTP Authenticator enhance security?

It provides a second factor of authentication by generating unique, time-sensitive passwords that change frequently. This means even if your primary password is compromised, an attacker would still need the current OTP to access your account.

### Can I use FreeOTP Authenticator offline?

Yes, FreeOTP Authenticator can generate one-time passwords even when your phone is in airplane mode or has no internet connection. The generation of OTPs is based on a shared secret and the current time, not on network connectivity.

### What services is FreeOTP Authenticator compatible with?

It works with many popular online services like Google, Facebook, and GitHub. It also supports private corporate security systems that implement the standardized TOTP or HOTP protocols, such as FreeIPA.

### Is FreeOTP Authenticator free to use?
