Same token for same user

[Eko]

Hi.

First of all, thank you for your great work.

Just a couple of questions:

Why is a new token generated on each login ? Is that just for simplicity or there is any other reason ?

Another question: we have a mobile app that's authenticating against our  grails api (with this plugin) when we use an external provider (Facebook) we retrieve FB token on mobile app, pass that token to the api, api validates the token against FB and return our own token to the mobile app. We made a controller / service for this. Is this feature supported by your plugin ? 

Regards and thanks again,
