There are a lot of recommendations here to stop using SSO. Unfortunately, there are enough number of sites that accept only SSO to make it impractical. One could go the route of I-refuse-to-use-any-site-that-does-not-provide-email-auth . This is something I have personally tried and find annoying to see sites that have only SSO (sometimes, only one provider that I do not even use). OTOH, if it something I really need or find interesting I fold and use SSO :(
