What are the default username and password for the cloud server?

The default username and password for a cloud server depend on the operating system and the cloud provider's configuration.

1. Linux-based servers:

   • Default username is often root (for direct root login) or a generic user like ubuntu, centos, or debian (depending on the OS image).
   • The default password is typically not set for security reasons. Instead, users are required to set a password during the initial setup or use SSH key authentication.

   Example: If you launch a Ubuntu-based cloud server, the default username is ubuntu, and you’ll need to authenticate via an SSH key or set a password manually after first login.

2. Windows-based servers:

   • Default username is usually Administrator.
   • The default password is either set by the user during deployment or generated automatically by the cloud provider and sent via email or console notification.

   Example: For a Windows Server instance on Tencent Cloud, the default username is Administrator, and the password is either user-defined or retrieved from the Tencent Cloud console.

For Tencent Cloud, if you forget the password or need to reset it, you can use the Console Password Reset feature under the CVM (Cloud Virtual Machine) management section. For Linux servers, Tencent Cloud also supports Key Pair authentication for secure SSH access.
