Ugh! MFA

I am trying to use Microsoft Graph to read/write an Excel spreadsheet stored in SharePoint. It’s an ugly process to start with — they don’t exactly make it easy to find the right ID numbers so you can reference the spreadsheet in the first place, but I finally got the proper URL. And then I tried to do the password-based token authentication.

{“error”:”invalid_grant”,”error_description”:”AADSTS70002: Error validating credentials. AADSTS50126: Invalid username or password\r\nTrace ID: b43d1973-c253-4889-8756-354e5bd77200\r\nCorrelation ID: 9cf94602-9d72-4790-8dcc-6cf0471058f9\r\nTimestamp: 2019-01-08 00:01:47Z”,”error_codes”:[70002,50126],”timestamp”:”2019-01-08 00:01:47Z”,”trace_id”:”b43d1973-c253-4889-8756-354e5bd77200″,”correlation_id”:”9cf94602-9d72-4790-8dcc-6cf0471058f9″}

Hint: the password isn’t wrong. I’ve seen a lot of comments online about this meaning the secret is wrong — which seemed reasonable, since I’m not seeing any auth traffic against the user account. But if you put in a known bad secret, there is a different invalid secret error.

{“error”:”invalid_client”,”error_description”:”AADSTS70002: Error validating credentials. AADSTS50012: Invalid client secret is provided.\r\nTrace ID: 59f4c7c8-73ab-4adb-bf15-10250a190d00\r\nCorrelation ID: 0a95810c-19e2-4fc6-a7be-c0ca7235d824\r\nTimestamp: 2019-01-08 00:00:37Z”,”error_codes”:[70002,50012],”timestamp”:”2019-01-08 00:00:37Z”,”trace_id”:”59f4c7c8-73ab-4adb-bf15-10250a190d00″,”correlation_id”:”0a95810c-19e2-4fc6-a7be-c0ca7235d824″}

But we use MFA … and I’ve got no way to perform the MFA validation. Sigh!
