Hello and thanks for the reply!
My initial thought with username and password was that if there was one password, other people who should not have access would know the password pretty soon. With a username – every member has a number so the username is the number – I thought it would be more secure because people connect their number with responsibility to keep “their” account private.
However, if that is not possible, unique passwords are fine as well. Is there a plugin that would make that work?
Note: The page that should be password restricted is not some kind of super secret information so no worries about the security.
