===
The authentication method is abstract so that it can easily be implemented for various users and use cases.
```
// bin/telebit-relay.js
state.authenticate() // calls either state.extensions.authenticate or state.defaults.authenticate
// which, in turn, calls Server.onAuth()
state.extensions = require('../lib/extensions');
state.extensions.authenticate({
state: state // lib/relay.js in-memory state
, auth: 'xyz.abc.123' // arbitrary token, typically a JWT (default handler)
})
// lib/relay.js
Server.onAuth(state, srv, rawAuth, validatedTokenData);
