When resetting your password through CAIS, it's important to remember that all RACF-related fields on the login screen must be filled out before you click on Log In.
The Password field should be the password you are looking to change or the temporary password that the technician has given to you over the phone.
Your New Password can not be any of your previous 7 passwords, and must be between 5 and 8 characters long. Ideally, it should contain an UPPER case letter, a lower case letter, and a number. The RACF password can not contain any non-alphanumeric characters (e.g. !@#$%).
