<a name="line-4"></a>A user is uniquely identified by their 'UserId'. A user can have one
<a name="line-5"></a>or more authentication methods associated with their account. However,
<a name="line-6"></a>each authentication method can only be associated with a single
<a name="line-7"></a>'UserId'. This means, for example, that a user can not use the same
<a name="line-8"></a>openid account to log in as multiple different users.
<a name="line-9"></a>
<a name="line-10"></a>Additionally, it is assume that all authentication methods associated
<a name="line-11"></a>with the 'UserId' are controlled by a single individual. They are not
<a name="line-12"></a>intended to provide a way for several different users to share the
<a name="line-13"></a>same account.
<a name="line-14"></a>
<a name="line-15"></a>An email address is also collected to make account recovery easier.
<a name="line-16"></a>
<a name="line-17"></a>Authentication Method
<a name="line-18"></a>---------------------
<a name="line-19"></a>
<a name="line-20"></a>When creating an account there are some common aspects -- such as the
<a name="line-21"></a>username and email address. But we also want to allow the user to
<a name="line-22"></a>select a method for authentication.
<a name="line-23"></a>
<a name="line-24"></a>Creating the account could be multiple steps. What if we store the
<a name="line-25"></a>partial data in a token. That way we avoid creating half-a-user.
<a name="line-26"></a>
<a name="line-27"></a>From an API point of view -- we want the client to simple POST to
<a name="line-28"></a>/users and create an account.
<a name="line-29"></a>
<a name="line-30"></a>For different authentication backends, we need the user to be able to
<a name="line-31"></a>fetch the partials for the extra information.
