There's a great project called Portier [0], which does this quite nicely. I highly recommend it. It's a successor of sorts to the ill-fated Mozilla Persona project [1]. > Portier (pronounced "Por-tee-ay") is a self-hostable login service that you can use instead of passwords. Portier sits between your website and third-party services like Google Sign-In to provide your users the fastest and easiest login experience, without ever needing a new password.
