Choose your website platform first. For WordPress, OpenCart and other sites on your own hosting, an admin account and FTPS/SFTP are often enough. You do not need every method. Your hosting provider can help find file access details.
Shopify uses separate app and Theme Access connections for store data and theme code. Webflow and Horoshop use their platform account or the private browser, rather than ordinary FTP. HTML sites prioritize file access. Unknown platforms offer the full list.
WordPress API: Users → Profile → Application Passwords. This is a separate application password, not your normal sign-in password. Hosting, SSH and database access are needed only for relevant tasks. Enter passwords and keys only in protected fields, never in chat.
For the WordPress API, enter your WordPress username, a generated application password and your site address: example.com, www.example.com or https://example.com. A /wp-json/ address also works; retain the subdirectory if WordPress is installed there. Beemlix uses HTTPS and handles redirects between www and the main domain. A publicly available API does not confirm sign-in. For an authentication error, check the application password; if the credentials are correct, ask your host to check that Authorization reaches WordPress. Your normal admin password is not an API password.
