Discover netlify/gotrue Open Source project by Netlify (@netlify)

User management for APIs

GoTrue is a small open-source API written in Golang, that can act as a self-standing API service for handling user registration and authentication for Jamstack projects.

It's based on OAuth2 and JWT and will handle user signup, authentication and custom user data.

Configuration

You may configure GoTrue using either a configuration file named .env, environment variables, or a combination of both. Environment variables are prefixed with GOTRUE_, and will always have precedence over values provided via file.
