Welcome to 2FAuth Docs
2FAuth is a web based self-hosted alternative to One Time Passcode (OTP) generators like Google Authenticator, designed for both mobile and desktop.
#
Why 2FAuth
Two-Factor Authentication has become very popular in recent years resulting in more and more situations where we face a security code request and an increase in the number of accounts protected by this technology. In other words it is now inevitable and critical.
The purpose of 2FAuth is to ease you perform your 2FA authentication steps whatever the device you are using, with a clean and always suitable interface. In front of your computer without your smartphone and dealing with a code request? No problemo, just open your 2FAuth instance in a browser tab et voila!
Moreover, as an open source and self-hosted application, it lets you regain control over your personal security data, whether about their privacy or the ability to backup them (did you already loose a smartphone with all your 2FA accounts in and only in Google Auth? I did... it really sucks)
