A list of popular sites and whether or not they accept two factor auth.

The goal of this project is to build a website (TwoFactorAuth.org) with a list of popular sites that support Two Factor Authentication, as well as the methods that they provide.

Our hope is to aid consumers who are deciding between alternative services based on the security they offer for their customers. This project also serves as an indicator of general security efforts used on a site.

If you would like to contribute, please read the entire guidelines here in CONTRIBUTING.md.

TwoFactorAuth.org is built upon Jekyll, using the github-pages gem. In order to run the site locally, bundler, and all other dependencies will need to be installed, and afterwards Jekyll can serve the site. If the gem command is not available, Ruby with RubyGems needs to be installed. Once Ruby and RubyGems are installed and available from the command line, TwoFactorAuth can be setup using the following commands.

gem install bundler
cd ~/twofactorauth
bundle install
bundle exec jekyll serve

If you're using Ubuntu or Bash on Windows (WSL) you'll probably need to install these dependencies first:

sudo apt install build-essential ruby-bundler ruby-dev make gcc g++ zlib1g-dev

The TwoFactorAuth website should now be accessible from http://localhost:4000.

Another option is to run Jekyll inside a Docker container. Please read the Jekyll Docker Documentation on how to use Jekyll.
