"Magic logins" to my news website?

Many websites let you sign in using Facebook or Google. For myself, I hate that. Those guys don’t need to know everywhere I go.

I just learned about an app called Pico that has something called a “magic signup” that lets prospective site users to sign in using their email – instead of Google or Facebook.

Anything like this for use with Infusionsoft? Thanks.
