Mozilla's BrowserID is a great implementation of verified email that lets you quickly and easily login to websites. This is an OmniAuth strategy that allows you to use BrowserID in your application!
gem install omniauth-browserid
BrowserID works using a Javascript-driven popup window. As such, there is a little more work than usual to integrate BrowserID seamlessly into your app. That being said, a default implementation of BrowserID will work as outlined below.
To use the built-in form in order to authenticate with BrowserID, you simply need to add the strategy to your application:
use OmniAuth::Builder do
provider :browser_id
endNow all you need to do is redirect your users to /auth/browser_id and you're all set!
To better integrate BrowserID with your application, you will want to use the BrowserID javascript directly in your app. Assuming you included the middleware as described above, here is a way you could structure your HTML:
<html>
<body>
<form id='browser_id_form' action='/auth/browser_id/callback'>
<input type='hidden' name='assertion'/>
<button type='submit'>Login with BrowserID</button>
</form>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
<script src="https://login.persona.org/include.js" type="text/javascript"></script>
<script type='text/javascript'>
function loginViaEmail() {
navigator.id.get(function(assertion) {
if (assertion) {
$('input[name=assertion]').val(assertion);
$('#browser_id_form').submit();
} else {
window.location = "#{failure_path}"
}
});
}
$(function() {
$('#browser_id_form button').click(function() {
loginViaEmail();
return false;
});
});
</script>
</body>
</html>What this does is sets up a form with a "Login with BrowserID" button. When the button of the form is clicked, it is intercepted by jQuery and the BrowserID flow is started. BrowserID returns an assertion that is then used to verify an email. In this example, the form points to /auth/browser_id/callback which will automatically perform verification as well as return a standard OmniAuth hash.
These are the options you can specify that are relevant to Omniauth BrowserID:
:verify_url- The verifier URL (defaults tohttps://verifier.login.persona.org/verify):name- The URL at which the strategy will be available (defaults tobrowser_id):audience_url- The host of your site. Defaults to thefull_hostof OmniAuth (either automatically determined or determined by theOmniAuth.config.full_hostoption):client_options- Any additional options to send to the Faraday connection.
