You’ll first have to add a password and then you could connect. If you setup a Windows 10 user account without adding a password, you won’t be able to connect to the shared folder. By default, when connecting from another machine, you have to enter the username and password of an account that has access to that shared folder on Windows 10. Lastly, you can decide how you want users to access the folder on Windows 10. You may have to first click on the Change settings button at the top before you can select a box. Scroll down until you see File and Printer Sharing and make sure that it is checked for the Private network. Then click on Allow an app or feature through Windows Firewall. Go to Control Panel and click on Windows Defender Firewall. The next thing you need to do is make sure that File and Printer Sharing is turned on and allowed through the Windows Firewall in Windows 10. This way, you’ll be able to access the folder from any computer or device without having to worry about entering credentials. If you want to make it easy and the folder doesn’t have sensitive data, just add the Everyone group and give them Full Control. Click on Permissions and then add groups or users that you want to give access. Check the Share this folder box and then give the share a name.

I suggest clicking on Advanced Sharing as you have more fine-grain control over everything.
