FreeOTP
Open source implementation of the two-factor authentication HOTP and TOTP schemes.
What is FreeOTP?
FreeOTP is a two-factor authentication application for systems utilizing one-time password protocols with support for Android (3.0 or later) and iOS (7 or later). Tokens can be added easily by scanning a QR-code or by manually entering in the token configuration.
FreeOTP implements open standards. This means that no proprietary server-side component is necessary: use any server-side component that implements these standards. We personally recommend FreeIPA, which uses TOTP. However, any standards-compliant implementation will work. Currently, FreeOTP provides implementations of HOTP and TOTP.

It's simple to use, but it's not possible to backup the secrets. This is very important because if you don't have a backup you have to manualy reset the 2FA for every service. Android users should use andOTP instead.
Just got a new Android and there's no way for me to get the OTPs from my iPhone to my new phone. What a pain.
Would be great if the app was a bit prettier and could be backed up.
OK, Great. Let it be better alternative to Authy than everything else. But the real reasons why do I using Authy are "syncing" and "windows". The last one is the same reason I am looking for alternative. Unfortunately there are no native version for linux, only as chrome app. Why dont you guys making software for PC? It looks like nowadays everyone just forget about existence of such platforms like linux or windows...
In fact, TOTP is safest when only used on a separate physical device where your passwords are. So if you store your login passwords on your PC, then the TOTP keys should be on your phone. This is the point of 2 factor authentication: if your passwords/PC is hacked, the attacker won't get into your account without the TOTP keys. If your phone is stolen, the attacker will have TOTP keys but no login passwords.
