Old AD User Account Password

Enter your account ID and old password below for verification.


Example:
  • MS Office 365 (O365) account ID
    e.g. chanwg10-c, wongmw-f, chengzq-x, lamjc
  • AD account ID

Password Tips:
  • it must be 8 - 64 characters in length.
  • it must be alphanumeric '0-9', 'a-z' and 'A-Z', e.g. c6A4h89O1.
  • it must include at least 1 Uppercase letter, 1 Lowercase letter and 1 digit.
  • it is case-sensitive, e.g. "acbbb" is not equal to "ACBBB".
  • allow special characters
    ! $ ' ( ) * , - . / ; < > ? @ [ \ ] ^ _ ` { | } ~
  • alternatively, use a passphrase no longer than 64 characters for added security, containing a series of words not commonly found in literature or music preferably with spaces, punctuations and unexpected characters that are unique or specific only to you.
  • it must not be the same as the three immediate preceding passwords that you have used.
  • It must not contain your account name or display name.
    For example, if your display name is "Chan Tai Man", the password cannot contain "chan", "tai" or "man" that are case-insensitive.
  • It cannot be changed again within 30 days, so pick a good password before you confirm a change.
  • It will expire in 180 days, meaning that you have to change password again in at least 180 days. You may wish to take note of the date that you have changed password then change it before it expires so as to avoid unfamiliar password prompts or being temporary cut off from services.
  • Mobile device users are recommended to refer to "Change Password Tips for Mobile Device User".

Notice You need to restart your PC and login using the new password to make it effective for all network services.
