Changing the Login Password on an ECS

Scenarios

This section describes how to change the password for logging in to an ECS when the password is about to expire, the password is forgotten, or you are logging in to the ECS for the first time. It is a good practice to change the initial password upon the first login.

You are advised to reset the ECS login password on the management console by referring to Resetting the Password for Logging In to an ECS on the Management Console.

Prerequisites

The ECS can be logged in.
