Out of the box, Google Identity Toolkit provides a fully functioning login flow, designed to get users into your site as quickly and easily as possible. Check out our password-only or federated login demo sites to see it in action.
The design embodies the very latest of our user experience research. If you have any questions or concerns about our features, we ask that you first check out our documents on the Account Chooser and the step-by-step description of our login flow.
Still have concerns? Post your question on our forum and we'll get back to you as soon as possible.
