Shopify for user registration
Hi fellow HNers. I'm working in a start-up and while we are good web design/UX, we aren't web app geniuses.<p>Especially with the Firesheep debacle in mind, we're looking to see if there's any services out there that will handle user registration and log in for us.<p>Kind of like Wufoo + log in.<p>With thousands of apps all needing this common functionality, surely there's something out there?<p>Thanks!
