Must be authenticated to use '/drive' syntax

Question

I have registered a 'Personal Microsoft accounts only' application via azure portal and given permission to 'File.ReadWriteAll' and set the relevant user as the owner.

By using the endpoint, https://login.microsoftonline.com/consumers/oauth2/v2.0/token i have retreived the access token, please note here, i have set below parameters,

• scope = https://graph.microsoft.com/.default
• grant_type = client_credentials

But, when i try https://graph.microsoft.com/v1.0/drives to view the drive items, it returns the error, 'Must be authenticated to use '/drive' syntax'

Hi @Fazlyn

For personal accounts, you should use delegated permissions and auth code flow to request the token, because you must authenticate the personal account itself and not the application.

Hope this helps.
