I want to be clear about this password to access workgroup computers and
folders/files.

My understanding is this:

I create a user for the workgroup computers that exists on the computer
trying to acess these files......this profile name has the SAME password or
am i not able to duplicate passwords?

For example, if userone wants to access computers 2 and 3 in the workgroup,
does username need the same name (userone) on all other machines and have the
same password or same name but different password?

I'm not 100% clear on this and want to get the right advice. Thanks.
