I'm not sure if this has been addressed yet, but one thing that would be great is supporting login from email, Facebook, Google, etc. to the same account.
This has been a big pain point for us with a Meteor based application where we allow email, FB and Google login. If you signed up with email and then try login with Google or the other way around, it won't let you and it's been quite a pain point for our users over the years. This was using the Meteor user-accounts suite.
There are some security concerns here, but a user should be able to sign up with email, then the next day login with Google, get sent an email getting him to confirm these are the same accounts, and then being able to login with either Google or password in the future.
