Giving access to an editor on CMS on an exported domain

I have a problem figuring out how to make an editor account on my site when I’ve exported it. The form appears but it says invalid when I try to make a user from my exported site.

I am wondering if it is possible to edit the site without it being on webflow since I don’t want my client to know the tools I work with.

Thanks a lot for your help

Not possible. Either you work with Webflow, or you don’t.

As I understand you can whitelabel the cms part. So you can put your logo in where it says webflow. So the client would think you made the awesome cms editing function.
