1) Go to the Websites & Domains tab.
2) Click FTP Access.
3) Click Create Additional FTP Account.
4) Type the account name and password the user will use to log in. You can also set the home directory here to restrict this user to a certain directory.
5) Click OK.
Below, we can see the new FTP account that was just added.
This is the end of the tutorial. You now know how to create additional FTP accounts in Plesk.
