RealMe is an authentication service that enables you to prove who you are online. Your RealMe login is a single username and password you can use to securely access online services.
The authentication process is run by the Department of Internal Affairs, which takes privacy and security very seriously. They were the first government service to be awarded the Privacy Trust Mark.
The RealMe website provides a general explanation, and an extensive list of users including government organisations, companies and other councils.
