Reset the root password

Set a new root password from the server's page. Nothing on the machine is touched: files, services and sessions all carry on.

Steps

1. Open the server from Servers.
2. In Connect, next to Password, press Reset… to begin.
3. Type RESET PASSWORD in the box and press Reset the password.
4. Copy the password, then press I've copied it.

Log in with it

Use the SSH line from the Connect card, and paste the new password when it asks. If you can't reach the server over the network at all, use the Console tab on its page, which works without the network: see Locked out of SSH.
