 In most cases, you want to create a key whenever you create (i.e. register) a new user. [`Auth.createUser()`](/reference/lucia/interfaces/auth#createuser) includes a parameter to define a key. `null` can be passed to `key` if you don't need to create a key. This preferable to using `Auth.createUser()` and `Auth.createKey()` consecutively as the user will not be created when the key already exists.
