I really like Persona. I use it (with the browserid gem for sinatra) for a couple of my side projects, as the only login option. It works great when it works and developing without having to bother about password management is great, though I first had to get my head around how that concepts works, serverside, that I have to remember an email address of a user in the database to assign him special rights (example: admin of a blog). What I didn't like, though granted, some of that is not very universal: 1. I made a small user test with it, and all user failed to complete the login, iff the email was new to persona. Because then, the new account has to be activated by email, and the link in that email lead to the persona account management. All users were confused by that and asked for confimation what to do, when confronted with the email confirmation message, and all of them got stuck in the new tab with that account management and were unable to return to the registration page on its own. I understand that it is possible to change that link, though I didn't find that parameter at that time and marked it as an issue to fix later (A quick search just now showed nothing). And it might be a gem thing. Still, bothered me. 2. I would have loved a demo mode that works offline (maybe that exists?). Had spotty internet for a while and it was very bothersome to test the persona part of the project, as the registration/login worked only every 10th time, if at all. That was so cumbersome that I stopped working on it till I got a better connection. Which also means that a user with a bad connection won't have fun with persona, not resilient enough. 3. I don't like that the name was used for another FF-Project before (FF-designs, if I'm not mistaken) - if that confused me at first, it might confuse users. Have no better alternative though (maybe I would just brand it Email Login). 4. The browserid-gem for sinatra doesn't work with ruby > 1.9.3, and the maintainer does not fix the issue even though there is a working patch in a pull request. So instead of just having to specify the gem in my gemfile, I have to provide the link to the alternate github implementation. I hate that, that does not feel safe. I tried to look up how a gem might be replaced with another one and found nothing about how that (or the gem infrastructre in general, note that this was while having no really usable internet connection) work.
