Changing your password

In advanced account security mode, passwords must have:

• at least fifteen characters
• at least two uppercase alphabetic characters
• at least two lowercase alphabetic characters
• at least two numeric characters
• at least two non-alphanumeric (special) characters
• not more than two consecutive repeating characters. That is, two repeating characters are allowed, three are not

In advanced account security mode, a new password must be different to the previous 10 passwords that have been used with an account.

In advanced account security mode, if a user logs in with a correct but expired password the MCU asks that user to change the password. If the user chooses not to change it, that user is allowed two more login attempts to change the password before the account gets disabled.

In advanced account security mode, users other than administrator users are not allowed to change their password more than once in a 24 hour period.

If the MCU is not in advanced account security mode, there are no criteria for password selection.

If the MCU is in advanced account security mode, the above criteria for passwords are displayed on the Change password page.
