Hirama666 i was trying to update all the usernames and passwords for the new year. i could't find this fields in the Update existing students drop down
This is correct, you can't update the username or password.
As for the username, this is logical as updating it is not a good idea anyway. Usernames are account identifiers and identifiers should not change.
Hirama666 What is the proper way to Generate generic Username & Password so Students can login.?
- Select "Create Students" from the dropdown
- Select "Generic: RosarioSIS ID" from the Username dropdown
- Select "Generic: Username + extra:" and fill the extra field below

Now, it is recommended to create usernames yourself using for example, the email address, or the "firstname.lastname" convention, etc.
As for passwords, generic passwords can be easily guessed by other students. So, they are not recommended either.
