How can a bearer token be generated in Azure IoT Central?

A bearer token in Azure IoT Central can be generated using the Azure CLI command az account get-access-token. This command is part of the Azure CLI toolset, which provides a way to interact with Azure services from the command line. When executed, it retrieves an OAuth 2.0 access token that you can use for authentication when making REST API calls or accessing resources in Azure IoT Central.

This method is particularly useful for developers and administrators who need to programmatically obtain tokens without manual authentication processes. The access token generated contains all necessary claims and permissions to access resources, making it a secure way to authenticate requests.

The other methods for generating a bearer token, while they may offer user interfaces or configuration options, do not directly correspond to the standard practice of obtaining tokens through command-line interfaces designed for automation and scripting. Thus, the command-line approach stands out as a more versatile and efficient way to manage access tokens in Azure IoT Central.
