To access your server's root shell you will have to generate your SSH key and add it to your server's authorized keys.

How to generate SSH key

Unix-like systems (PC)

1. Open the terminal.
2. Run the following command:

   ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519
   

   You will be asked to enter a passphrase. You can leave it empty, but it is recommended to use a passphrase. If you do not want to use a passphrase, press Enter.
3. Print the public key to the terminal and copy it:

   cat ~/.ssh/id_ed25519.pub
   

4. Refer to the next section to add the key to your server.

Windows

1. Open settings and under "Applications" click on "Manage additional components".
2. Press "Add Component".
3. Enter "OpenSSH client" in the search box and install it.
4. Open the Command Prompt. You can do this by pressing Win+R, typing cmd and pressing Enter.
5. Run the following command, replacing user_name with your Windows username:

   ssh-keygen -t ed25519 -f C:\Users\user_name\.ssh\id_ed25519.pub
   

   You will be asked to enter a passphrase. You can leave it empty, but it is recommended to use a passphrase. If you do not want to use a passphrase, press Enter.
6. Print the public key to the terminal and copy it:

   type C:\Users\user_name\.ssh\id_ed25519.pub
   

   Once again, replace user_name with your Windows username.
7. Refer to the next section to add the key to your server.

   ssh-keygen -t ed25519 -f /data/data/com.termux/files/usr/etc/ssh/ssh_host_ed25519_key
   

   You will be asked to enter a passphrase. You can leave it empty, but it is recommended to use a passphrase. If you do not want to use a passphrase, press Enter.
3. Print the public key to the terminal and copy it:

   cat /data/data/com.termux/files/usr/etc/ssh/ssh_host_ed25519_key.pub
   

4. Refer to the next section to add the key to your server.

How to access your server's root shell via SSH

1. Open the terminal or Command Prompt.
2. Run the following command, replacing server_domain with your server's domain:

   ssh root@server_domain
   

3. Enter the passphrase you entered when generating the SSH key, if you used one.

Be careful when using the root shell. If you do not know what you are doing, you can break your server or leak your data. Responsibility for the consequences of your actions lies with you. Respect the privacy of other users.
