Apple changes name Apple ID to Apple Account
Apple is changing the umbrella name for login credentials from Apple ID to Apple Account. According to the company, the new name should provide a more consistent login experience. There will be no further changes to the login details that users already have.
Starting with the recent release of iOS 18, iPadOS 18, macOS Sequoia, and watchOS 11, Apple mentions users' login credentials in their own words an Apple Account instead of an Apple ID. Nevertheless, there is a lot support pages the old name is still mentioned, so notes MacRumors. User login details have been called 'Apple ID' since the beginning of this century.
For example, despite the name change, Apple uses its account management page the old name. Source: Apple
