On OpenRent [1] we're using the Google Identity Toolkit [2]. We're finding that in our current configuration it works extremely well, even for non technical users. It offers password-less log-in, and also remembers your username/email client-side. The only issue is lack of support for facebook/twitter log in out of the box - but that is apparently in development. It doesn't seem to be widely adopted, and that is possibly due to the reliance on Google servers it adds to your service. Whether that comes back to haunt us or not I don't know - but I have a backup system in place in case GITKit does stop working!
