In this session we will see 4 options of getting an access token to get Microsoft 365 data (groups) from Microsoft Graph. All this will be done in an Azure function (daemon and/or non-daemon application).

- We will start with the basic setup of creating an app registration, providing Microsoft Graph permissions to it and then use it’s credentials in an Azure function to get the data from a calendar.
- We will then add a managed identity to the Azure function, provide Microsoft Graph permissions to it and use the managed identity’s credentials to get the data from a calendar.
- We will also have a look at how we can apply the same concept to get data from a custom API.

By the end of the session the attendees will get an overview of the authentication libraries provided by Microsoft and will be in a position to understand which library to use in the next Azure application.

All the code will be shared on GitHub.
