Yo Paul, I'm sorta biased here -- I work at Stormpath, so I think you should use us, but I did want to mention what we do which I personally think is cool (I use Stormpath myself for all my own side projects): - You can use us for SSO (something like having login.mysite.com). - You can use us to build your own user management system directly -- you can build a registration / login page on your site, and in the backend, use our open source libraries to create / manage / edit users on Stormpath. - You can use us to for 'hosted login' -- basically when a user wants to register / login to your site you redirect them to us, and we'll display your own custom registration / login page, handle the authentication, then send the user back to you (new feature). - We have social login (although we only support two providers atm: Google / Facebook). - It's really easy to export your data out of us. I built a tool which does is really fast / well: https://github.com/rdegges/stormpath-export https://github.com/rdegges/stormpath-export - Our framework integrations are top notch. I've specifically been working on our framework integrations (check these out!): - http://flask-stormpath.readthedocs.org/en/latest/ http://flask-stormpath.readthedocs.org/en/latest/ (Flask) - http://docs.stormpath.com/nodejs/express/ http://docs.stormpath.com/nodejs/express/ (Express) If you're using Flask or Express, there's no simpler way to do user authentication (and if there is, let me know, so I can fix it!). Anyhow, if you do end up rolling with Stormpath, and we don't work well, let me know why. I'm not an owner or anything, but totally 100% love working on the product here. I think it's the best solution out there. I'm r@rdegges.com (personal) if you wanna chat.
