If you wish to add another FTP account, start by going to Files > FTP Accounts in your cPanel dashboard.
Create a username and password for this FTP account. The username will take the format of an email address (unlike SFTP where just the username is entered, for standard FTP accounts the full address is used). In the example below we are creating an account for user2@example.com.
After putting your username and password into the designated areas, you’ll see that a directory has been created for that user:
If you want the new user to have FTP access to the full account, then you will want to delete the domain and user info from the directory field so it looks like this:
If you leave the domain and user information in the directory box, the new FTP account will only have access to the specified directory. If you want to restrict the user's access to another directory, like public_html, then you can enter that into the directory field.
You also have the option to set a Quota for the account or you can leave it set to Unlimited.
After you have the account set up the way you want it, click Create FTP Account.
