I always prefer a 1:1 relationship with providers: that is, an account that's tied directly to me rather than through a third-party provider like Twitter, Facebook, or OpenID. (Aside: why is social media managing my passwords? On the third option, it's great in theory and terrible in execution.)

My biggest issue with Flickr is that they tie it to a @yahoo.com email address. I know it's part of the "ecosystem", but c'mon—who uses one of those?

I've always made a policy of not signing into things with Facebook. FB recently tried to encourage people to do so more often by allowing you to prevent them access to your data, or even sign in without letting the website know who you are at all, but that doesn't solve the problem where it's Facebook I don't trust with my Flickr data and not vice-versa.

What Flickr data would be fed to Flickr if you did the Facebook sign in option? Besides the fact that you use Flickr, that is.

> This is (kind of) one of the reasons that I don't use third party services to sign in to anything

When you say "this", what are you referring to?

I can see not wanting one company to always know when you're logging into other companies (hence the lure of Persona), but this particular situation (you can no longer use third-party authentication after eight years or whatever and must now use first-party authentication) doesn't seem like a reason at all.

you are a huge minority in this regard

Not as huge as you probably think.

It is the top comment and having a username+password option is still reassuring even if you choose to go with facebook or another third party anyway. Many will only use facebook to login if there are alternatives.
