@iskitsas
Do we want to save the users in our system in a separate table?
I feel we should not save users as it might lead to security concerns, we can just use oauth2 to get the token and access endpoints.

@Sanskar95 ,
You can use oauth2. Just take into account how are you going to handle the different roles/permissions, and what is accessible to whom.

[Sanskar95]

@iskitsas yeah totally

We can setup roles permissions using matchers easily
But have to create endpoints so that admin can change permissions for that we definitely gonna require a table store usernames and current role.
