Hellō is an identity network that provides login and registration using the standard OpenID Connect protocol. Hellō offers your users choice between all popular social login providers.

This Fastify package provides an endpoint that handles all protocol interactions and sets an encrypted cookie with the logged in user's information. The cookie contents are decrypted and available as req.getAuth().

See the Fastify Quickstart documentation for how to add Hellō to your Fastify app in minutes, and the Fastify SDK documentation for details.
