If you’d like to give people view only access to the directory and access to pages only members and guests are able to see you can create a guest user.
To create a guest user go to users > add new and create a user. The username, email and password can be anything you want. For user role select “Guest”. Create the user and you can give the user and password to anyone you’d like to be able to login and view the directory but not edit.
