I need to allow someone temporary access to installing amazon checkout buttons on my wordpress website. I went under security in my Cpanel and created a user name angie and a password for my public_html directory. How will the person get to it from the internet and did I create the password the right way in order for him to access it from the web. My website is fashionsdivastyle.com. When I go there, it doesn't recognize angie. Does he access it from my wordpress site under user?

How do I give him temporary access to add the amazon pay button to my wordpress site?

Please advise
