# Decentralized login

Use the Authentication Protocol spec to get a high level overview of the proposed system design behind Handshake login.

If you're looking to see how we implemented login with Handshake on services like [Namer News](https://news.namebase.io), or you're looking to create an OIDC provider yourself for an application you're building, use the Implementation Guide.
