Add myself to a Github organization

Question

I just received login credentials for a Github organization. How can I add my personal Github account to the organization?

When I try to log into the organization, I get the following error message:

That account is an organization, you can't log in to it. Try your personal account instead.

Answer 1

I think an organization is not an account. An administrator or more are assigned to an organization and he/she/them manage it. You must to login using your administrator account credentials and then you can manage your organization.
