We are working on a Mobile app, that works with Jira Cloud, we checked that there is two Authentication Methods shared in Rest API documentation OAuth 2.0 and Basic Auth.
I've tried Atlassian Mobile app Jira Cloud, and noticed that they have a different way to authenticate, is it possible to know the method used and where we can found a related documentation.
By the way does OAuth 2.0 authentication fit for Mobile App?
