Ask HN: What authentication methods do you prefer?

I use FB, Google accounts but only on sites I trust. If I don't trust the site and there is no classic u/p system then I leave

Why would you sign up on untrusted sites?

There's a difference between "I trust this website with access to my primary online identity" (Google/Facebook) and "I trust this website with a made-up username, one-off password and throwaway email address".

How do you determine whether to trust a site or not?

Why not just use username/password? It sucks in well-known ways and quantities, and usually less than the alternatives.

Just be sure to store the passwords properly (bcrypt or somesuch).

I generate random passwords for every site, I don't like SSO provided by Facebook, Twitter and Google etc, its insecure and places the trust in a single companies hands.

If you don't allow me to register normally (i.e. without a single signon mechanism) I likely won't register.
