/**
 * Passport Model
 *
 * The Passport model handles associating authenticators with users. An authen-
 * ticator can be either local (password) or third-party (provider). A single
 * user can have multiple passports, allowing them to connect and use several
 * third-party strategies in optional conjunction with a password.
 *
 * Since an application will only need to authenticate a user once per session,
 * it makes sense to encapsulate the data specific to the authentication process
 * in a model of its own. This allows us to keep the session itself as light-
 * weight as possible as the application only needs to serialize and deserialize
 * the user, but not the authentication data, to and from the session.

    // When the local strategy is employed, a password will be used as the
    // means of authentication along with either a username or an email.
    //
    // accessToken is used to authenticate API requests. it is generated when a
    // passport (with protocol 'local') is created for a user.

    // Provider fields: Provider, identifer and tokens
    //
    // "provider" is the name of the third-party auth service in all lowercase
    // (e.g. 'github', 'facebook') whereas "identifier" is a provider-specific
    // key, typically an ID. These two fields are used as the main means of
    // identifying a passport and tying it to a local user.
    //
    // The "tokens" field is a JSON object used in the case of the OAuth stan-
    // dards. When using OAuth 1.0, a `token` as well as a `tokenSecret` will
    // be issued by the provider. In the case of OAuth 2.0, an `accessToken`
    // and a `refreshToken` will be issued.

    // adapter compatible with associations.
