• Security: SSH key applies the asymmetric encryption mechanism, which help reduces the risk of brute force attacks.
• Convenience: With the SSH key, you can access the target VM instance quickly without entering the password.
• Restriction: You can use SSH keys to access Linux VM instances as root users.

1. Create a SSH key pair and keep the private key well.
2. Attach the SSH public key to a VM instance.
3. Upload the SSH private key to the access terminate, and run ssh -i ${private_key.pem} ${UserName}@${IpAddress} to log in to the VM instance.

Note: In the login command, ${private_key.pem} refers to the private key file path, ${UserName} refers to the username, and ${IpAddress} refers to the IP address of the VM instance to be logged in to. For example,

ssh -i private_key.pem root@172.20.20.149

For more information, see Log in to VM Instance with SSH Key.
