If you want to log in to an ECS using VNC provided on the management console, log in to the ECS using an SSH key, configure the login password, and use the password for login.
To log in to a password-authenticated ECS for the first time, use either of the following methods:
- For logins using VNC on the management console, the login username is root.
  For details about how to log in to the ECS using VNC, see Remotely Logging In to a Linux ECS (Using VNC).
- For logins using an SSH password, the login username is root and the ECS must have an EIP bound.
  For details, see Remotely Logging In to a Linux ECS (Using an SSH Password).

If you have added a data disk during ECS creation, you must initialize the data disk after logging in to the ECS.
For details, see Scenarios and Disk Partitions.
Certain ECSs require the installation of a driver after you log in to them. For details about available ECS types and functions, see ECS Types. For details about restrictions on using different types of ECSs, see their notes.
