WebDav authentication with 2FA enabled

I am trying to connect to our own ownCloud install using the users WebDav url.
The user also has 2FA enabled

The Mac OSX desktop client can connect (does it use webdav)
When ANY client tries to connect I get an authentication failed error.

How can I authenticate WebDav when 2FA is enabled?

With the ownCloud desktop and mobile clients, you can enable OAuth 2.0 app on the server. Then clients use the browser window to login, so users can enter their second factor.

For third party WebDAV applications, users can generate an App Password in the user settings, that can be used instead of the primary one.

Yes, than ks - creating App Passwords was the solution - thanks.
