Modifying a Password Policy

Updated at: Mar 25, 2021 GMT+08:00


This section describes how to set password and user login security rules as well as user lock rules. Password policies set on MRS Manager take effect for Human-machine users only, because the passwords of Machine-machine users are randomly generated.

If a new password policy needs to be used for a new user's password or the password modified by the user, perform the following operations to modify the password policy first, and then create a user or change the password by following instructions in Creating a User or Changing the Password of an Operation User.

Modify password policies based on service security requirements, because they involve user management security. Otherwise, security risks may be caused.


  1. On MRS Manager, click System.
  2. Click Configure Password Policy.
  3. Modify password policies as prompted. For parameter details, see the following table:

    Table 1 Password policy parameter description



    Minimum Password Length

    Indicates the minimum number of characters a password contains. The value ranges from 8 to 32. The default value is 8.

    Number of Character Types

    Indicates the minimum number of character types a password contains. The character types are uppercase letters, lowercase letters, digits, spaces, and special characters (~`!?,.:;-_'(){}[]/<>@#$%^&*+|\=). The value can be 3 or 4. The default value 3 indicates that the password must contain at least three types of the following characters: uppercase letters, lowercase letters, digits, special characters, and spaces.

    Password Expiration Notification Days

    Indicates the number of days in advance users are notified that their passwords are about to expire. After the value is set, if the difference between the cluster time and the password expiration time is smaller than this value, the user receives password expiration notifications. When a user logs in to MRS Manager, a message is displayed, indicating that the password is about to expire and asking the user whether to change the password. The value ranges from 0 to X (X must be set to the half of the password validity period and rounded down). Value 0 indicates that no notification is sent. The default value is 5.
