ApsaraDB for HBase supports user authentication. You only need to configure a username and a password for user authentication. The password is stored in ciphertext on a server. The encrypted password is transferred for user authentication. This prevents data from being reused or forged if the ciphertext is intercepted. This topic describes how to use Lindorm Insight to manage users.

Prerequisites

You are logged on to the cluster management system of your Lindorm cluster. For more information, see Log on to the cluster management system.

Create a user

  2. Click + Create User on the right side of the page.
  3. In the Create User dialog box, specify User name and Password.

    Note
    • After you create a user, the password of the user cannot be viewed in the system. If you forget the password, you must change the password.
    • A user does not have any permission after it is created. You can manually grant permissions to the user you create. For more information, see Grant permissions to a user.
