- For Linux instances, the default username is root.
- For Windows instances, the default username is Administrator.
Note: You must restart an instance after its password is reset, which has an impact on your service. To reduce the impact, we recommend you to reset the password when the related service is not busy.
To reset the instance password, perform the following:
Log on to the ECS console.
In the left-side navigation pane, click Instances.
Select a region.
Select the target instance. You may select multiple instances with identical operating statuses.
Click More > Reset Password.
Enter a new password in the displayed dialog box. Click Submit.
Select the instance on which the password was changed and click Restart.
Note: The new password only takes effect after the instance is restarted through the console. Restarting directly within the instance do not apply the new password.
Click OK in the displayed dialog box to restart the instance.
