List of 2FA dongle providers and the platforms they support.
The goal is to build a website (dongleauth.info) with a comprehensive list of sites that support One Time Passwords (OTP) or Universal 2nd Factor (U2F).
Our hope is to aid consumers who are deciding between alternative services based on the security they offer for their customers. This can also serve as an indicator for the effort a site has put into security in general.
This site is a fork of TwoFactorAuth. The fork is necessary to further differentiate the 'Hardware' section. The TwoFactorAuth projects wants to give a general overview and do not wants to mark the technical details as well. We respect this decision. In need of a differentiation between OTP and U2F we decided to fork the project. Please see the note on definitions as well.

DongleAuth.info is built upon Jekyll, using the github-pages gem.
In order to run the site locally, it is necessary to install bundler, install all dependencies, and then use Jekyll to serve
the site. If the
gem command is not available to you, it is necessary to install Ruby with RubyGems.
Once Ruby and RubyGems are installed and available from the command line, TwoFactorAuth can be setup using the following commands.
gem install bundler cd ~/dongleauth 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 libffi-dev nodejs python-dev gcc ruby rails make zlib1g-dev ruby-dev libcurl3 gem install bundler
The DongleAuth website should then be accessible from
