ApsaraDB for Redis allows you to create multiple database accounts for an instance. You can grant these accounts different permissions, such as the read-only, read/write, and replication permissions. This helps you flexibly manage instances and minimize user errors for data security.


The database engine version of the instance is Redis 4.0 or later.
Note If the engine version of an instance does not meet this requirement, you can upgrade the version. For more information, see Upgrade the major version.


You can create a maximum of 20 accounts for an ApsaraDB for Redis instance.


  1. Log on to the ApsaraDB for Redis console and go to the Instances page. In the top navigation bar, select the region in which the instance is deployed. Then, find the instance and click its ID.
  2. In the left-side navigation pane, click Account Management.
    Note If your instance runs Redis 4.0 or later and does not support the Account Management feature, you can update the minor version of the instance. For more information, see Update the minor version.
  3. Click Create in the upper-right corner of the page.
  4. In the panel that appears, configure the parameters that are described in the following table.
    Parameter Description
    Account The account name. It must meet the following requirements:
    • The name can contain lowercase letters, digits, and hyphens (-) and must start with a lowercase letter.

Q: Why does an account already exist after an instance is created?

A: A default account whose name is the instance ID is automatically created after an instance is created to ensure data security. The password of this account has been specified when you create the instance. The password can be reset if you forget it.
