A developer account is created for you on the Apple Developer website (developer.apple.com/account) after you accept the Apple Developer Agreement. You’ll use your developer account to download beta software and tools, visit forums, and report bugs. If you join a paid program, you’ll see additional membership-related options in your account, such as your team information, access to Certificates, Identifiers & Profiles, code-level support, and more.
To learn about these programs, go to Apple Developer Program and Apple Developer Enterprise Program. For developer account documentation, choose Help > Developer Account Help (or go to Developer Account Help).
