NameID ====== With namecoin, you can register names corresponding to online identities of the form "id/something", which can hold your email address, real name, other contact info, public key fingerprints, or whatever else you desire. Furthermore, since ownership of a name is associated to possession of a corresponding private key, one can proof it using a signature with that private key. OpenID is a system which allows you to sign into a plethora of websites using a single identity, which is provided by some OpenID server (the identity provider) or your choice. NameID now tries to combine both ideas by implementing an OpenID identity provider which allows anyone owning a id/ identity to sign into it, authenticating with a private key signature. You don't have to (and can't in fact) register an account with NameID and also don't need to remember a password, because the first is done by registering an id/ name with the decentralised namecoin network, and the second is replaced by your name's private key.
