Here's a plain English summary of this rule:
If you have a login and password to use the court's electronic system, you're the one responsible for keeping them safe. This means you can't share your login information with someone else or let it fall into the wrong hands. Whatever happens under your account is your responsibility.
If you ever think someone else has gotten access to your login or password, you need to act fast. You must change your password or update your account information right away to protect it from further misuse. Waiting too long to fix a security problem could leave your account open to someone using it without your permission.
This rule exists to protect both you and the court system. Since electronic filings and account access can affect real legal deadlines and case information, keeping your login secure helps make sure no one else can act on your behalf or see information they shouldn't.
