Genau der richtige Authenticator

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

Won't load new QRs

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.

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

Crashes on iOS 12

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.

FAQ

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?

Yes, FreeOTP Authenticator is completely free and open-source software. It is licensed under the Apache 2.0 license, meaning you can review and modify the source code.
