2013 and we still haven't really gotten to a good, universal single-sign on system. OpenID seemed like it was going to get us there (at least to me), but nowadays many sites moved away in favour of Google or Facebook or Twitter specific logins, often asking for a little more rights than I'm comfortable giving them. Still, anything is better than signing up to a site with a username and password, and receiving a mail with your account info in plain text. Since the LinkedIn and Twitter hacks, I've lost faith in the backend developers to treat the storage of account info with the respect they deserve. (at least use a hash and a unique salt per user...)
