Tokens and authentication

Users can sign in within their Office 365 account to get Calendar and OneDrive information. 

Authentication is done using the Microsoft identity platform (MS Identity Client documentation) to retrieve a valid token that is used for accessing Microsoft Graph API (MS Graph API documentation). 

As authentication is done in Launcher mobile apps, the Microsoft token is sent to Launcher Windows securely through RabbitMQ using TLS. This token is never stored, and it is completely forgotten once users disconnect or the application is closed.
