Here is a patch to make the Token field a textarea.

@eidoscom, sometimes the bearer token is build by another source and we can not control the size.

If we face this problem then we can change the field from textfield to textarea. sounds good solution.

I think the most coherent approach is to keep the field type as 'textfield' and limit the allowed characters to 512. The editing ease and user experience provided by a 'textarea' field make no sense in this scenario, where only an authorization token will be pasted.
