Example: If you are using AlmaLinux, the username will be almalinux.
----Access root----
If you want root access, you must first log in using the default user of your instance's operating system (such as ubuntu, almalinux, freebsd, etc.).
Then run the following commands:
sudo su -passwd root
This will allow you to set a password for the root user.
After that, open the SSH configuration file:
nano /etc/ssh/sshd_config
Make sure the following options are set:
PermitRootLogin yesPasswordAuthentication yes
After making these changes, save the file and restart or reload the SSH service. The exact service name and command may vary depending on the operating system.
Once the changes have been applied, test the SSH connection with the root user in a new tab.
Important: We do not recommend enabling root access with password authentication due to brute-force attacks.
