Rails API : Best way to implement authentication?

Question

I\'m writing a Rails 4 app that will expose an API for a mobile app that\'s yet to be developed. Users will authenticate using an e-mail and password from the mobile app.

Answer 1

Tiddle gem provides Devise strategy for token authentication in API-only Ruby on Rails applications. Its main feature is support for multiple tokens per user.
