Microservice Authentication strategy

by

Based on what I understand, a good way to resolve it is by using the OAuth 2 protocol (you can find a little more information about it on http://oauth.net/2/)

When your user logs into your application they will get a token and with this token they will be able to send to other services to identify them in the request.
