You can reset an instance password if you forget the password, need to change the password, or have not set a password when creating the instance.
Log on to the Redis console.
Find the target instance and click the instance ID or Manage to go to the Instance Information page.
In the Change Password window, enter the old password and a new password and click OK.
If you forget your password, click Forgot Password in the Change Password window. Then you can set a new password in the Reset Password window.
The password must consist of 8 to 30 characters, including upper-case letters, lower-case letters, and numbers at the same time.
