If you want to store wifi passwords on a per-user basis, you should create user wifi connections, not system wifi connections. When creating the connection, uncheck the "Available to all users" check box.
Please be aware that even if wifi passwords are stored in the user's keyring, it is still trivial for the root user to obtain them.
