TwoFactorAuth.org

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

The Goal

The goal is to have a website with a comprehensive list of sites that support two factor auth as well as the methods that they support it.

This is to aid when deciding on alternative services based on the security they offer for their customers.

This also is a way for consumers to see what sites still need to invest in further security practices and which ones already do.

Contributing

All the data is managed through a series of Yaml files so it may be useful to read up on the Yaml syntax.

To add a new site, go to the data files and get familiar with how it is setup. There is a section and coresponding file for each Category and they all follow this syntax:

Guidelines

1. Don't break the build: We have a simple continuous integration system setup with Travis. If your pull request doesn't pass, it won't be merged.

   To manually test the build, just run the following:

   $ ruby verify.rb

2. Use a Nice Icon: The icon must be 32x32 in dimension. Earlier we were using 16x16 but upgraded for various high density screens.

3. Be Awesome: You need to be awesome. That is all.

New Sections

To add a new section, modify the sections value in main.yml and follow the template below:

sections:
  - id: category-id
    title: Category Name
    icon: icon-class

Then create a new file in the _data directory named the same as your section's id with the .yml extension.

New Sites

The values should be pretty straight forward for adding a new website. The websites array should already be defined, just add a new website to it like this example:

    websites:
        - name: Site
          url: https://site.com
          img: site.png
          twitter: twitter_handle   # To tweet at site, if tfa is No
          tfa: Yes
          goog: Yes
          authy: Yes
          sms: Yes
          doc: <url to the documentation>
          custom:
              - icon: android
                url: <url to a custom Android client>
              - icon: apple
                url: <url to a custom iOS client>
              # Any other custom clients...

Note: A tip on getting icons, use Google's icon api. Just go to https://www.google.com/s2/favicons?domain=http://example.com and you will get sites the icon as png.

Custom

The custom section is for an app or site that doesn't use SMS, Google Auth, or Authy. This app should have its own way of generating 2FA from within the app or a special 2FA service such as via email, yubikey, etc.
