Use MFA tokens for programmatic authentication in Sharepoint online

Question

Hi All,

In order to do the programmatic authentication in SharePoint Online, Can we use the MFA token in program for the authentication till the token expire?

We have an account in O365 and enabled MFA for the user account and the same user account is used for programmatic authentication. We want to avoid the every time second level authentication in mobile. We are looking for the feasibility to use the old MFA token.

MFA Token : Which we are getting in the registered mobile number during the SharePoint Online authentication.

Please let me know feasibility of this request.

Thanks & Regards
Suresh S

Hi @Suresh S ,
We are unable to skip the second level authentication in mobile. I would recommend you SharePoint App-Only to do the programmatic authentication in SharePoint Online.

Answer 2

token which you got from MFA-authenticated user will expire quite soon so you won't be able to use it for a long time. It is better to register AAD app, grant necessary permissions for this app, generate app secret or upload self-signed certificate to this app and use app permissions (=use token generated for this app).
