DigitAuth is a centralized authentication system, designed by Wervyn and MZXGiant in late 2007. Its aim is to link all services in the MegaZeux community to one authentication server, such that users can authenticate once to use all services that support it. This allows for DigitalMZX services to expand and encompass more of the community needs, while still allowing external services to use its massive database of user information in a secure manner.

Any user who wants to be a part of the community can sign up and will be instantly granted access to all services that support the DigitAuth API. As for services, any service that wishes to "subscribe" to the user database can do so. All requests to this system are encrypted and all data is secure. Even servers using the DigitAuth service cannot simply download a list of passwords from the central database. All requests are controlled and logged.
