I had a developer working on a website. Now I learned a bit of WordPress and I would like to continue some of the work on my own. I asked the developer for the passwords and he only gave me the passwords of the hosting account and not from the wp-admin of the WordPress installation. When I asked about those passwords he told me that he never used the wp-admin panel to develop the website and he doesn't know about any passwords about it. He refused to tell me also how he developed the website if not from the panel. Is this even possible? The only way to develop a website is from www.mysite.com/wp-admin, right?
Anyway I still have the passwords from the hosting account that means the ftp passwords and everything. Is the username and password of my website stored in one of the files that are on the ftp account? For example in the wp-config.php file or somewhere else? I can't understand if the developer simply wants more money for it, or I am missing something here.
