@rmuller: Thanks. I've documented this: https://winscp.net/eng/docs/guide_microsoft_onedrive#password

I tried on my side but not working. Did you put the password app on the Password field and let all other fields as the OneDrive config post or did you proceed with other modification?

@rmuller: Thanks for sharing your solution. Can you please give us more information about what is the "app password"?

Never mind, I solved it using an app password.

Following these instructions
Connecting securely to Microsoft OneDrive with WebDAV

I get the following error on login:

Could not authenticate to server: Missing Authentication-Info header
Connection failed.

What to do?
