 ## Two-Auth Methods

 ### `create()`
 
 Provide two-auth with a user ID and a phone number associated with that user.
 
     client.create(*USER_ID*, *PHONE_NUMBER*);

 `create` registers a new verification service with Twilio, which will allow your application to later send and verify codes to and from that phone number and user.

 `verify` will properly identify and `return` `true` if the code is valid, `false` if the code is invalid.
