Auth0 Guardian - Multi Factor Authenticator

Auth0 Guardian is like Google Authenticator but without the friction. You get a push notification, swipe left, accept, and you are logged in. It's second factor authentication made simple.

Note for developers: Auth0 Guardian is one of the multi factor authentication options that can be used within the Auth0 identity platform (https://auth0.com). You can enable it with a single switch and you can choose to support SMS as well. You don't have to change your apps to start supporting multi factor authentication.
