Password Change Compliance • HIPAA rules require that passwords are changed every six months. • The Admin Guide recommends changing passwords every 90 days. • In the past, you got an email. If the password was not updated, you got another email. • If you are in a HIPAA data group, you will likely see the new password change page in the next six months. • Always double check the URL at the top of the page to make sure it starts with https and is at stanford.edu before entering any information.
