A HoYoverse Account is the central login account system used by HoYoverse.
It is basically your universal HoYoverse Account ID that lets you:
- Use one set of credentials (email/phone + password, or linked social accounts) to log into all HoYoverse games and services.
- Sync your game progress across PC, mobile, PlayStation, and other platforms (when supported).
- Manage account settings in the HoYoverse Account Management website (password change, linked devices, account security, etc.).
- Enable security features like two-factor authentication to protect your data.
