What is my logon name when a workstation logs onto my Win10 computer?

I have a Windows 10 Professional that is part of WORKGROUP. When I log onto the computer, my full name comes comes and I enter my password (or use the four digit logon). I am the only user as well as administrator.

Here is where the question arises: if I want to sign onto my computer from another computer on the WORKGROUP, I need to use my first name and the password for my Microsoft logon - and I only discovered this by trying many combinations.

So, where might I find these credentials? And is there a place where I can read about this part of the security?

Many thanks...

Kari -

Yes, that did give the name of the computer and who is signed on. I know how to find the computer name; just not sure where to get the name of where the name(s) of users are located. Under Users, just my full name is present - not the user name - here I have been using Windows for more years than I want to admit and cannot remeber where the user name is located.

You will only find user names, not the whole credentials. I really don´t fully understand your question. Are you logging in via RDP? The list of user names can be obtain typing net users in CMD.

My problem/question arose when I setup Samba on my local server and was trying to access my Windows 10 computer from my Macbook computer. As expected, I was asked for the User and Password. Since when I'm at the Win10 computer, it comes up with my full name: Todd Cary and asks for a password - no problem.

But to login via the Macbook, I had no idea that the user is "Todd" since I have never used that, nor needed to. So, I kept trying different Users and Passwords until I found the combination. Where could that be stored?
