 | Name | Default | Description|
 |---|---|---|
-| **`change_headers_on_each_request`** | `true` | By default the access-token header will change after each request. The client is responsible for keeping track of the changing tokens. Both [ng-token-auth](https://github.com/lynndylanhurley/ng-token-auth) and [jToker](https://github.com/lynndylanhurley/j-toker) do this out of the box. While this implementation is more secure, it can be difficult to manage. Set this to false to prevent the `access-token` header from changing after each request.

 | **`token_lifespan`** | `2.weeks` | Set the length of your tokens' lifespans. Users will need to re-authenticate after this duration of time has passed since their last login. |
 | **`token_cost`** | `10` | Set the cost of your tokens' cost. The possible cost value is within range from 4 to 31. It is recommended to not use a value more than 10. For details see [BCrypt Cost Factors](https://github.com/codahale/bcrypt-ruby#cost-factors). |
 | **`batch_request_buffer_throttle`** | `5.seconds` | Sometimes it's necessary to make several requests to the API at the same time. In this case, each request in the batch will need to share the same auth token. This setting determines how far apart the requests can be while still using the same auth token.
