Authenticating to SharePoint Online site using CSOM
I've seen this error more than once. In most cases I just typed username / password wrong. Federated authentication should not be a problem but have you considered using App Credentials also? Are you using Multi-factor authentication?
PnP's AuthenticationManager Class provides some usefull utility methods to obtain an authenticated context in different ways. Could you try using GetWebLoginClientContext for getting an authenticated context?

SolutionConnecting to SharePoint Online using PnP PowerShell Connect-PnPOnline allows you to specify a UseWebLogin parameter. This allows you to connect with MFA enabled. Once connected you'd have many more https://github.com/SharePoint/PnP-PowerShell/blob/master/Documentation/readme.mdat your disposal
